If you get your head round this you'll see that this much higher value is what you expect to be the _published_ velocity curve. It is nothing like the true velocity. ....but nobody except you and I has ever considered using the green brightness curve to calculate the source velocity. The penny still hasn't dropped - what everyone has always been doing is measuring the actual shift which in your model is TDoppler, the combination of both V and A parts, and then publishing "velocity" curves by using the equation that would be applicable if _only_ VDoppler existed. To do a comparison with those published curves, you need to plot that false velocity - what I thought was your red curve. I now have a third model. The compression of individual photons is much 'diluted'. It is nothing more than handwaving, you have given no equations, and it nonsense both physically and mathematically but laying those aside, it would still affect both curves identically so we don't even need to consider it. Your whole argument is based on the clasical wave theory of light ...which is known to be wrong. My theory is perfectly sound. Yes, and a little consideration of Fourier analysis tells you that must be the case. You have it correct Henry, now just add the red curve to the plot so we don't have to use a calculator to get the figures. Here is a summary of our current findings: Let's start with some more fundamental findings. The effects we see are the result of TDoppler. Ballistic theory defines the speed that every part of a wave travels hence tells us without any further consideration what the effects will be. What you are calling a 'wave' is the property of a very large group of photons. You have successfully modelled the luminosity variation as a function of the orbital parameters as your green curve. The same curve on a linear scale can be used for the velocity curve with a simple scale conversion. The velocity curve is a direct measure of TDoppler. Luminosity variation can be a combination of TDoppler and intrinsic variation. VDoppler is negligible for stars. ADoppler alone produces very accurate brightness curves. Only if the orbital velocity you use is that determined by conventional theory. You have claimed before that the values used by astronomers are much too high and that is a valid conclusion from ballistic theory. This certainly appears to be true for pulsars. VDoppler requires assumptions about the intrinsic brightness of cepheids to match their brightness curves. The only assumption is that intrinsic variation can increase the total variation which is not a problem. If it required that intrinsic variation was synchronised and 180 out of phase so that it reduced the total I would object. OK Both ADoppler alone and VDoppler alone can produce the correct shape and phasing of associated OBSERVED velocity curves. The curve is due to TDoppler, there aren't two different mechanisms, just the different dependencies for a single effect. I would say there are. ....and ADoppler exists only in the BaTh. But if the ADoppler velocity curve is the same as its brightness curve then the velocity variation is far too high. Pulsars seem to fo;;ow VDoppler predictions but, if pulsar curves are matched with the BaTh curves, then all currently calculated pulsar velocites are far higher than the true ones. VDoppler could be correct in all instances....but I have now suggested a possible alternative explanation for this. The correct statement is that TDoppler can be correct in all instances. That leads to the conclusion that your "extinction distance" is quite small and similar for all types of stars which to my mind is a bonus, not a problem. I have no idea why you are objecting to that conclusion. My objection is that I couldn't produce my brightness curves with VDoppler alone. And nor does VDoppler, there would be no Doppler whatsoever because they would be launched with the same "absolute wavelength" as you called it regardless of speed. In BaTh, the VDoppler effect is independent of distance. If gratings are purely wavelength dependent, they shouldn't detect VDoppler. Ah but they do, however that is not a problem. You are forgetting your "cars on the motorway" analogy. Speed equalisation means that the light is moving at c when it reaches us and since the frequency must be unchanged the wavelength becomes altered. Whether gratings measure frequency or wavelength becomes moot because both will give the same answer. OK Let's assume that. ADoppler takes place while the source is accelerating.. No, it is caused by the acceleration at the point of emission but it takes place during propagation just as the conversion of VDoppler from fixed wavelength - variable speed to variable wavelength - common speed. Both require that photons be fully compressible. I'm not sure if I fully agree with this. You are again trying to apply classical wave theory to ballistics. The problem is we don't really know what 'light wavelength' is. Is it solely related to the properties of individual photons or is it a group thing? In reality, we don't even know that individual photons exist. No, their wavelengths stay the same. Yes, that's what I meant. After leaving their accelerating source, they experience no further changes. Right, but since photons from the sources have the same "absolute wavelength" at emission regardless of the speed of the source (a point you have made many times), if they are incompressible then there is no VDoppler either. The effect of speed equalisation would be to slow down or speed up the photons until they were travelling at c while leaving their wavelength unaltered. By the time they reach us they would all be moving at c and all have the same wavelength so they would all have the same frequency too. Whatever method is used to measure them, there would be no Doppler effect whatsoever. Incompressible photons simply doesn't work. Ah! no, I qualified my statement by pointing out that they DO change 'length' every time they experience a velocity change. They are 'compressible' but the 'ends' don't continue to move relatively AFTER the acceleration...not for long anyway. My red curve merely showed the phase position of photon arrival compared with their phase of emission. There was no change in wavelength from the original VDoppler. That's why it was wrong. It wasn't wrong... but it wasn't designed to do what you want it to do. OK, but it was wrong in the context of modelling ballistic theory. Showing a red curve, or even just putting two scales on the same curve, one log in magnitudes and the other linear in km/s, will give you the true ballistic theory prediction. ....easier said than done..... Then you just match the velocity curve with whatever parameters you like and you can claim your match and then see what it tells you about the physics of space. Incidentally, if you do a search for "Methods to Account for Interstellar Extinction" you will find thousands of references that might be useful. I have made my case that you can succeed with just two very credible assumptions - that Cepheids have some intrinsic variation that adds to the TDoppler effect and that eclipses sometimes happen. You can then match all the experimental data, including fitting to the empirical Shapiro delay curve, and the result says speed equalisation is a short distance effect for _all_ stars. Your alternative is building a model that contradicts ballistic theory and requires space properties that depend on the period of the star that produced the light passing through it. Henry, it is very odd but I seem to be in the position of telling you why ballistic theory works for this limited test, and you are telling me why it doesn't! ....but I suspect you want to eliminate ADoppler altogether...and hence throw the BaTh out with it. What's going on here? Of course it still fails Sagnac and it predicts the wrong sense for the Shapiro delay (which is why you can only fit an empirical curve) but I'm curious to know why you are arguing against me. Phase George, Phase. I'm not actually arguing...I'm keeping an eye out for bigger things that might come out of this. I like my latest theory. "Photons are much less compressible than their groups".

Otherwise it could easily be one star orbitted by a small cool object with a period of 0.21 days. This highlights what I have been saying. ADoppler curves are virtually identical to genuine eclipsing curves. Only accurate spectral data can separate the two. I suspect that many presumed eclipsing binaries are not that at all.

Only if you apply the VDoppler equation. That's right Henry. Try to get your head round this, please. When astronomers take a series of spectra from a star in a binary system they calculate the ratio of the frequency or wavelength shift to the mean value for any spectral lines and multiply by the speed of light to get the value that is published as a velocity curve. Yes I know that George. Then you also appreciate that we need that curve on your program in order to do any comparison. I can take the 300 km/s value from the graph of EF Dra below and convert that into "Linear = 1.002" manually but it would be easier if you just displayed it. Have you any idea how much extra work that would involve? A one-line change to convert the value you currently display as the "linear" number from unitrs of magnitude to units of km/s. It could read: Mag. Change =0.32019 (Log) = 87772 km/s (peak to peak) Obviously a linear (red) plot as well as the green log plot would be nice but just putting the value on the screen would be a start. Presenting hte output so that hte curves can be magnified has given me quite a few headaches already, particularly for the log curves. ...but just for you I will have a go... You could just add a text line giving the value but displaying the curve with a horizontal axis and a scale would avoid the doubt you had some time ago about a factor of two difference if the figure is orbital velocity or peak-to-peak variation. True. The magnitude change figure is actually the ratio maximum/minimum brightness....so it's 'peak to peak'. OK, so above I have doubled the 43886 km/s I posted before. Your value should be around that ballpark. Anyway you then simply adjust your orbital parameters to match that number and the curve shape to the published velocity curve and you have your match. Whether you reduce the speed, alter the pitch or reduce the equalisation distance is up to you but my feel is that you will find using the same equalisation distance as for the pulsars gets you a solution and logically we should expect that to be the case. No, we have found it is dominant for pulsars and we don't know for stars but we will in a moment. The only evidence I have that it is dominant for pulsars is that it is the only way I can match the curve of PSR1913+16 accurately. The first evidence we found was J1909-3744 where the Shapiro delay gives the orbital phase but both are consistent and I suspect J0737-3039 will give much the same though you haven't tried it yet. However, the way such curves are statistically produced, leaves a great deal of room for error. Maybe a constant light speed is even assumed in their making. More excuses Henry? I love your approach - "I can't match the curve but there is room for error in the measurement therefore I can claim I match it." I CAN match the curve very accurately George. I haven't seeen you match the amplitude of any velocity curve yet, your example of EF Dra is too high by a factor of nearly 150. ...but I can also produce a very similar curve with ADoppler completely dominant. TDoppler Henry, your ballistic theory equations produce TDoppler and there is no room in it for alternatives. If you are familiar with the way these curves are produced ...'epoch matching' or something like that. You gave me a reference to the technique It was someone else I think but basically all it means is that any one point is the average of all the readings at the same phase over many cycles. ...then you will be aware of the potential for inaccuracy. Sure, things like sensor drift can cause problems. The scatter of the readings gives the error bars but there should always be some indication of systematics. It is quite possible that this curve was actually fiddled a bit to match the anticipated VDoppler one. Accusing people of fraud again Henry? Sorry but if your theory can't handle reality, don't go blaming the guys who took the readings. That's OK, I have consistently been saying you have no choice but to include both VDoppler and ADoppler, they aren't really different things, just different terms in the single TDoppler equation. It is possible that VDoppler is needed to match pulsar curves but it doesn't apear to be required in the case of star curves. It doesn't matter what is needed, ballistic theory includes both factors, period. It appear that 'photon compressibility' is VDoppler determined but the curve shape matches ADoppler. No, what appears is that it seems the equalisation distance is small for Cepheids too and most of the luminosity variation is intrinsic. Right, I think I have a possible picture now. We have two possibilities. What you just could be correct...and any variations from the pure Keplerian curve are also intrinsic. Variations from a Keplerian orbit could only be due to other bodies and you are severely limited as to what configurations could be stable. Post-Newtonian factors will likewise be small other than systematic drift of parameters over many years like PSR1913+16. Over a few orbits these are negligible. Wait, I stated that wrongly. I am assuming that these are huff puff stars. ..in which case the radial velocities of expansion and contraction follow a similar curve to that of a star on Keplerian orbit. No, you still don't seem to undertsand how they work. I didn't get a chance to respond to an earlier post of yours about this. the mechanism was described in the presentation I cited some days back. Basically as the star contracts, the pressure and density rise and importantly it reaches a point where it becomes opaque. The radiation is trapped, pressure builds rapidly and the outer layers start to expand. They become more transparent again but momentum carries the material out until stopped by gravity and it starts to fall back. The process is more like someone on a trampoline. What I meant was that the little peak at the top of the RT Aur curve could be intrinsic and VDoppler could produce the curve. I can produce it very accurately with just ADoppler....BUT the velocity range is then seemingly too large. Ballistic theory only allows you to use TDoppler, you can't choose to use only some parts of an eqaution. There cannot be a difference Henry, basic physics and even pure maths rules it out (Fourier analysis). Ballistic theory says that any electromagnetic disturbance moves at "c+v" (that's shorthand as usual) and that applies to any waveform shape whether a simple sine wave or a complex signal. If you think of a burst of a sine wave of some duration, it carries some finite energy and contains a number of cycles. There is therefore an amount of energy in each cycle. The brightening occurs because more cycles arrive in a given time than were transmitted in the same time due to bunching, but that increased number of cycles in a given time is also obviously the frequency change factor. Whatever you do to modify the speed of propagation, the green and red curves we have talked about are rigidly linked. As you have said yourself in justifying not drawing the extra curve, the two are identical with just a different scale. George I am just realising how amusing you are. You keep telling me that if one piece of evidence refutes a theory then the theory is wrong. You often refer to sagnac as an example. Yes, ballistic theory is undoubtedly wrong, this is purely a hypothetical discussion to see what the consequences would be if it were correct. Yet you are trying to use the classical wave theory of light to prove my ballistic theory wrong when it has been firmly established that the wave theory itself is wrong. .. IT BREAKS DOWN AT THE P.E. EFFECT. Classical wave theory was around for a long time before it was quantised. Ballistic is still in the wave theory region, it has not yet been quantised. Before you can attempt that, you need to know what the wave interpretation says and then when you try to quantise it one of the constraints you must meet is getting your quantum version equations to give the same result as the wave version when averaged over large numbers of photons. Sure it can be used to model interference patterns and such but it cannot explain anything about the particle nature of light. Of course not, it doesn't attempt to yet. Wave theory might work well in relation to the behaviour of groups of photons...but it doesn't tell us anything about the partical nature of individual photons or the way they travel through space. Nor does LET, SR or any other current theory .. The current full theory is QED which amalgamates SR and QM in flat space. .. except the ballistic one. Nonsense, you don't have any quantum equations equivalent to ballistic theory at all. Perhaps we should revise ballistic theory as you seem to be losing the plot a bit. Ritz said light was emitted at c relative to the source. De Sitter suggested that was untenable because binaries would show multiple images. That is true for spectroscopic binaries so to try to get round that a new theory was produced which included "speed equalisation" The current theory has three parts: 1) The universe is Galilean invariant 2) Any electromagnetic disturbance initially propagates at c relative to the source. 3) The speed relative to the medium through which the disturbance propagates varies as it progresses as described by the differential equation: dv/ds = (c/n - v)/R where n is the refractive index R is a characteristic distance Both n and R depend on the medium. n also depends on the frequency of the wave however it seems R does not since the orbital parameters of a binary would then vary with the optical band in which it was measured. My current view is that wave theory should work for pulsars because the pulses are made of groups of photons. Both the pulse widths and the spacing between pulses should behave as wave theory says. Similarly, my brightness curves are based on the relative movements and aggregations of vast numbers of photons and should be an accurate simulation. In the case of individual photons however, there is absolutely no reason to believe the same principle applies. It cannot be assumed that the actual 'wavelengths' of photons making up the light in each 'macro pulse' experience the same compression or rarification that the pulses do. It is not an assumption, it is a mathematical identity. Think about the Fourier transform of a pulsed waveform. Also remember the fact that the peak intensity from a grating cannot be different if you analyse it by two different approaches. The experiment is often done in undergraduate work, get a line from a grating with a bright source and then dim it until a photomultiplier shows individual photons arriving. You can watch a histogram build up to show exactly the same probability as the wave theory intensity. To match the brightness/velocity phase relationship of cepheids, I need ADoppler to dominate. Tough luck, the universe isn't going to change to suit your needs. Ballistic theory says the result is due to TDoppler, end of story. Therefore I propose that photons are indeed ADoppler sensitive but to a much smaller degree than are the pulses themselves. You don't get to"propose" anything Henry, you write down the equations for ballistic theory, which I have done above, and then you calculate what they predict. To quantise the theory, you write down a new set of equations that apply to photons and then you calculate what those predict. For instance if the pulses compress by a factor of 1.5, the photons may do so by only 0.0015 or less. That's not what the equations say. If you think of photons as discrete entities then this is a quite conceivable theory ...not just a wild guess. In summary, individual photon 'compression' DOES occur when the source is accelerating ... but the effect is much smaller than it is in the case of the relative movements of all the photons in a group. This way, the brightness/velocity phasing of star curves is correct and the doppler shifts are of the right order. So, even though a brightness curve might match perfectly and vary by 1.5 or so (linear), the actual spectral shift is diluted to only a very small fraction of that value. I'm wondering if there isn't a time dependent term in the 'compressibility equation'. Does a second order effect come into play? (da/dt) da/dt is the derivative of the acceleration. For a circular orbit, v = sin(wt) where w is the angular frequency or 2 pi / P where P is the orbital period. a = dv/dt = w cos(wt) da/dt - -w^2 sin(wt) It would come in as one more order than acceleration so would be roughly a factor of 1/P less than the basics we have discussed. For a one day orbit it would be four orders of magnitude smaller or make a change of about 0.01% to your curves, not worth worrying about. 'a' goes from -1 through zero to +1. The difference ratio can be infinite. You need to revise your calculus Henry. ...The time interval between the emission of the 'ends of a photon' is much smaller than that between the pulses of a pulsar. Therefore, for a source in orbit, the velocity difference is much larger across the pulse that across the photon. So the pulse gap should compress relatively much more that will the photon. No, the speed difference is delta_v = a * t so the ratio of speed difference to time is linear. Only if a is constant.. No, a can vary in any way you like in which case delta_v is the integral of a.dt Anyway let's not delve too deeply into this because I suspect there is a far more important factor involved. INDIVIDUAL PHOTONS simply do not compress as much as the groups do. When (if ever) you quantise ballistic theory, you will start by taking the wave theory result and showing that the quantum version produces identical results for large aggregates. What I mean is that you can rely on the measurement of the shift. Photometry needs careful attention to comtaminating light, getting accurate calibration, CCD pixel sensitivity and so on but spectra have far fewer sources of systematic errors, especially when only the relative shift is needed and not an absolute wavelength measurement. ...well ther is still argument as to whether gratings are sensitive to 'wavelength' (absolute distance between wavecrests) or 'frequency' (rate of wavecrest arrival) Gratings produce a peak of intensity at the point on the screen where the reflected waves from each ruling arrive in phase. You should be able to answer the question simply by calculating that condition for an incoming plane wave. Yes, the classical theory is well established....but, without an aether, it is still not clear why gratings detect doppler shifts from moving sources. As I said, you need to analyse the behaviour of a grating in ballistic theory, but since you include speed equalisation it becomes quite simple, as the speed varies the waves are compressed (for v initially c/n) or stretched (for v initially c/n) and that changes the wavelength. SR certainly doesn't provide a 'physical' explanation. Of course it does, it even explains the second order effect which Ritz and aether theory get wrong. Don't waste your time trying to change the subject again Henry. The only requirements are that it should be a Keplerian orbit and the _TDoppler_ should match the published curve. Yes, I understand what you are saying. But in the simulation we DO know the correct blue curve...because that's what we start with. The blue curve represents the actual motion of the body which is an unknown under the Ritzian theory, in terms of the model it is not "known", it is the "independent variable" (technically a small number of variables, semi major axis and eccentricity for example). .....but in the simulation it is completely defined. No, in the sim it is the "independent variable". That like saying the operating frequency of a radio is not known but the position of the tuning knob is "completely defined". It is defined only in that there is a specific angle you turn it to for each station. We need a model that produces a brightness curve that is correct in both shape and mag. change but which also accommodates the compressible photon concept to a small extent. No, the theory requires that the waves change in a certain way. If you then go on from there to try to quantise the theory then it starts with the fact that a grating will produce a peak of intensity at some location and the photons are then partly defined by the fact that a photomultiplier will produce individual flashes with a distribution curve that is identical to the intensity curve. That's a bit of an oversimplification George. Not really Henry. If you try to quantise the theory you will probably start by adopting Planck's solution to the black body problem, then you will define the properties of a photon such that energy is conserved and wavelengths and frequencies match the wave theory you have at the moment and so on. I maintain that groups of photons behave differently from individual ones. The behaviour of groups is defined by the statistical formula that will form the basis of you method of quantisation. Have a think about what I said above. Should individual photons compress as much as the gaps between groups of photons or pulses? The relationship between acceleration and velocity is linear so the effect must be identical. We could talk about this forever Henry, there is a huge amount of evidence. For example we see the sodium doublet in the lab and also in stellar spectra. That doublet is the same as a modulated sine wave (what is called suppressed carrier) and any discrepancy would show up as harmonics or a change in the ratio of the separation to the centre frequency. that's ancient stuff.... side bands... I assume that's what you are saying... Exactly. We don't see any. The doublet is just due to a fine quantum level separation. I has nothing to do with what I'm taking about. The fact that we don't see extra sidebands tells you how waves behave and quanta are simple the smallest amount of energy for any given wave. Conservation of energy means wave cycles must arrive at a higher rate if the brightness is to increase, and cycle arrival rate is the definition of frequency. You're talking about 'E=h.nu' type brightness variation. No! E=h.nu will not work in ballistic theory as a general principle. It will berquired to solve the black body problem but can only apply at the point of emission. My guess is that ballistic theory will require a kinetic approach such as if a photon is emitted with speed c+v and arrives at speed c then the energy will be h*nu*(c/(c+v))^2 where nu is the frequency of emission in the source frame. However I think you have a _lot_ of work to do to make that work consistently. My brightness variation is caused by numbers of photons arriving per unit time. Yes, that's what I meant too. There is no room for any argument Henry, the red curve must be directly related to the green and your claimed match the luminosity curve of EF Dra gives a gross mismatch to the velocity curve. Not any more. Yes Henry, you haven't changed the ballistic theory equations so that's what they predict. The solution is simple, it doesn't falsify your theory and it works for pulsars and stars. Add the red curve and match it to the velocity curve. You can do that three ways. First you could reduce the size of the blue curve. That ties up with what you have said many times, that astronomers overestimate the velocity of orbits because they don't take account of ADoppler. Second you could simply increase the pitch. A nearly face-on orbit can reduce the radial velocity by a factor of 140 without too much trouble, though I think you'll find that all binary systems have to be face-on which raises difficult questions. The third method which I have been suggesting for some time is that the speed equalisation is a property of space and is similar regardless of the source of the light travelling through it. We had a six hour figure for the pulsar and I think it needs to be much less than that. there is no reason to think that the effect for other types of star would be any different and I anticipate that putting that number into the model for EF Dra will solve the problem. You haven't given me any reason at all why that modelling approach is not valid and it fully complies with ballistic theory while your suggestions are all at odds with it. I am claiming that, ... I am not interested in handwaving "claims", the equations do not predict what you are saying, your application of them is wrong. For the BaTh, ADoppler has to dominate otherwise photon waveshift will be all VDoppler and the phasing between the brightness and velocity will be 90 out. For the current ballistic theory, the equations say that the Doppler effect and the luminosity variation are both the TDoppler factor, end of story. If you quantise the theory, and I doubt you are capable of doing that, then there will probably be an additional variation of (c/(c+v))^2 to take into account, but that is not part of the current set of equations. At present, your simulation for EF Dra has the velocity grossly too high but you can correct it by reducing your equalisation distance to a value comparable to that for the pulsars. The conclusion is that most of the Cepheid variation is intrinsic and for EF Dra it is mostly due to eclipsing. George |

On Sat, 21 Apr 2007 10:33:43 +0100, "George Dishman" Then you also appreciate that we need that curve on your program in order to do any comparison. I can take the 300 km/s value from the graph of EF Dra below and convert that into "Linear = 1.002" manually but it would be easier if you just displayed it. Have you any idea how much extra work that would involve? A one-line change to convert the value you currently display as the "linear" number from unitrs of magnitude to units of km/s. It could read: Mag. Change =0.32019 (Log) = 87772 km/s (peak to peak) Well I can do that easily.... but it wasn't originally intended to be a velocity measurement. Obviously a linear (red) plot as well as the green log plot would be nice but just putting the value on the screen would be a start. Strangly, the linear and log plots with the same height have much the same shapes. That is, a linear plot at say 10 LYs looks the same as a log plot at maybe 30LYs. Presenting hte output so that hte curves can be magnified has given me quite a few headaches already, particularly for the log curves. ...but just for you I will have a go... You could just add a text line giving the value but displaying the curve with a horizontal axis and a scale would avoid the doubt you had some time ago about a factor of two difference if the figure is orbital velocity or peak-to-peak variation. True. The magnitude change figure is actually the ratio maximum/minimum brightness....so it's 'peak to peak'. OK, so above I have doubled the 43886 km/s I posted before. Your value should be around that ballpark. Anyway you then simply adjust your orbital parameters to match that number and the curve shape to the published velocity curve and you have your match. But then the brighness magnitude change is too low. Whether you reduce the speed, alter the pitch or reduce the equalisation distance is up to you but my feel is that you will find using the same equalisation distance as for the pulsars gets you a solution and logically we should expect that to be the case. Your suggestion works for pulsars because we don't have to match a brightness curve. For J1909-3744, I get an orbital velocity of only 100 m/s...but that includes the pitch angle. I would say that this pulsar is moving in quite a small orbit around the barycentre. More excuses Henry? I love your approach - "I can't match the curve but there is room for error in the measurement therefore I can claim I match it." I CAN match the curve very accurately George. I haven't seeen you match the amplitude of any velocity curve yet, your example of EF Dra is too high by a factor of nearly 150. Forget EF Dra now. It probably is an eclipsing binary. ...but I can also produce a very similar curve with ADoppler completely dominant. TDoppler Henry, your ballistic theory equations produce TDoppler and there is no room in it for alternatives. George, star brightness curves depend entirely on ADoppler, in BaTh. If you are familiar with the way these curves are produced ...'epoch matching' or something like that. You gave me a reference to the technique It was someone else I think but basically all it means is that any one point is the average of all the readings at the same phase over many cycles. That's the aim...but the method is based on fiddling with period until what looks like some kind of intelligent curve appears. The spread at each point is enormous and a best fit plot could be way out. ...then you will be aware of the potential for inaccuracy. Sure, things like sensor drift can cause problems. The scatter of the readings gives the error bars but there should always be some indication of systematics. It is quite possible that this curve was actually fiddled a bit to match the anticipated VDoppler one. Accusing people of fraud again Henry? Sorry but if your theory can't handle reality, don't go blaming the guys who took the readings. Well like I said, the ADoppler curve is very similar to the VDoppler one...and anyone who accepts constant c could be excused for assuming it was without intending any deliberate 'fiddle'. I'll show you the two curves for comparison. http://www.users.bigpond.com/hewn/george2.jpg I can probably make them even more similar than that if I try. That's OK, I have consistently been saying you have no choice but to include both VDoppler and ADoppler, they aren't really different things, just different terms in the single TDoppler equation. It is possible that VDoppler is needed to match pulsar curves but it doesn't apear to be required in the case of star curves. It doesn't matter what is needed, ballistic theory includes both factors, period. ....but VDoppler is negligible for stars....and I think I now know why. Variations from a Keplerian orbit could only be due to other bodies and you are severely limited as to what configurations could be stable. Post-Newtonian factors will likewise be small other than systematic drift of parameters over many years like PSR1913+16. Over a few orbits these are negligible. Wait, I stated that wrongly. I am assuming that these are huff puff stars. ..in which case the radial velocities of expansion and contraction follow a similar curve to that of a star on Keplerian orbit. No, you still don't seem to undertsand how they work. I didn't get a chance to respond to an earlier post of yours about this. the mechanism was described in the presentation I cited some days back. Basically as the star contracts, the pressure and density rise and importantly it reaches a point where it becomes opaque. The radiation is trapped, pressure builds rapidly and the outer layers start to expand. They become more transparent again but momentum carries the material out until stopped by gravity and it starts to fall back. The process is more like someone on a trampoline. Yes I know the basics George, I was trying to point out that the acceleration appears to be non symmetrical on either side of the mid point. It is not simple harmonic. There is more acceleration on the 'compression' side. There also might be a lack of acceleration symmetry on the inward and outward strokes at the same radius. Do you see what I'm getting at? The combination of these can give the impression of a Keplerian orbit if one goes by the radial velocity only. What I meant was that the little peak at the top of the RT Aur curve could be intrinsic and VDoppler could produce the curve. I can produce it very accurately with just ADoppler....BUT the velocity range is then seemingly too large. Ballistic theory only allows you to use TDoppler, you can't choose to use only some parts of an eqaution. Yes All right George. Just for you I'll refer to it as TDoppler in future. There cannot be a difference Henry, basic physics and even pure maths rules it out (Fourier analysis). Ballistic theory says that any electromagnetic disturbance moves at "c+v" (that's shorthand as usual) and that applies to any waveform shape whether a simple sine wave or a complex signal. If you think of a burst of a sine wave of some duration, it carries some finite energy and contains a number of cycles. There is therefore an amount of energy in each cycle. The brightening occurs because more cycles arrive in a given time than were transmitted in the same time due to bunching, but that increased number of cycles in a given time is also obviously the frequency change factor. Whatever you do to modify the speed of propagation, the green and red curves we have talked about are rigidly linked. As you have said yourself in justifying not drawing the extra curve, the two are identical with just a different scale. George I am just realising how amusing you are. You keep telling me that if one piece of evidence refutes a theory then the theory is wrong. You often refer to sagnac as an example. Yes, ballistic theory is undoubtedly wrong, this is purely a hypothetical discussion to see what the consequences would be if it were correct. It cannot be wrong. Emitted light has only one reference...ITS SOURCE. It must be emitted at the same speed wrt the source no matter how the source moves...unless of course an aether exists. Mind you, it only needs to be a 'local aether'. Yet you are trying to use the classical wave theory of light to prove my ballistic theory wrong when it has been firmly established that the wave theory itself is wrong. .. IT BREAKS DOWN AT THE P.E. EFFECT. Classical wave theory was around for a long time before it was quantised. Ballistic is still in the wave theory region, it has not yet been quantised. Before you can attempt that, you need to know what the wave interpretation says and then when you try to quantise it one of the constraints you must meet is getting your quantum version equations to give the same result as the wave version when averaged over large numbers of photons. Wave theory might explain RF signals and the change in separation of pulsar pulses but there is no reason to believe it relates in any way to individual photons. Sure it can be used to model interference patterns and such but it cannot explain anything about the particle nature of light. Of course not, it doesn't attempt to yet. But you are trying to make out it does. Wave theory might work well in relation to the behaviour of groups of photons...but it doesn't tell us anything about the partical nature of individual photons or the way they travel through space. Nor does LET, SR or any other current theory .. The current full theory is QED which amalgamates SR and QM in flat space. well I don't and wont accept it. .. except the ballistic one. Nonsense, you don't have any quantum equations equivalent to ballistic theory at all. Perhaps we should revise ballistic theory as you seem to be losing the plot a bit. Ritz said light was emitted at c relative to the source. De Sitter suggested that was untenable because binaries would show multiple images. That is true for spectroscopic binaries so to try to get round that a new theory was produced which included "speed equalisation" The current theory has three parts: 1) The universe is Galilean invariant 2) Any electromagnetic disturbance initially propagates at c relative to the source. 3) The speed relative to the medium through which the disturbance propagates varies as it progresses as described by the differential equation: dv/ds = (c/n - v)/R where n is the refractive index R is a characteristic distance Both n and R depend on the medium. n also depends on the frequency of the wave however it seems R does not since the orbital parameters of a binary would then vary with the optical band in which it was measured. Yes. What's wrong with that theory? In the case of individual photons however, there is absolutely no reason to believe the same principle applies. It cannot be assumed that the actual 'wavelengths' of photons making up the light in each 'macro pulse' experience the same compression or rarification that the pulses do. It is not an assumption, it is a mathematical identity. Think about the Fourier transform of a pulsed waveform. George, wave theory does not apply. The cars don't shrink when they slow down and bunch together on the highway. Also remember the fact that the peak intensity from a grating cannot be different if you analyse it by two different approaches. The experiment is often done in undergraduate work, get a line from a grating with a bright source and then dim it until a photomultiplier shows individual photons arriving. You can watch a histogram build up to show exactly the same probability as the wave theory intensity. That doesn't tell us anything about how a grating would behave if the source was moving. To match the brightness/velocity phase relationship of cepheids, I need ADoppler to dominate. Tough luck, the universe isn't going to change to suit your needs. Ballistic theory says the result is due to TDoppler, end of story. That's OK. I know ADoppler usually dominates. Therefore I propose that photons are indeed ADoppler sensitive but to a much smaller degree than are the pulses themselves. You don't get to"propose" anything Henry, you write down the equations for ballistic theory, which I have done above, and then you calculate what they predict. To quantise the theory, you write down a new set of equations that apply to photons and then you calculate what those predict. We might consider that photons change length only during an acceleration. ..but I don't think that could provide enough doppler shift to match observed ones. ADoppler needs to be accumulative but I am effectively proposing that the extinction rate 'within a photon' is much greater than 'between photons', So the ends of photons stop moving relatively long before whole photons do relative to each other. Get it? Now I can explain why the green curve is also the observed velocity curve but with a much higher magnitude change. For instance if the pulses compress by a factor of 1.5, the photons may do so by only 0.0015 or less. That's not what the equations say. I'm not interested in what classical wave theory may try to say about individual quanta. It doesn't apply. If you think of photons as discrete entities then this is a quite conceivable theory ...not just a wild guess. In summary, individual photon 'compression' DOES occur when the source is accelerating ... but the effect is much smaller than it is in the case of the relative movements of all the photons in a group. This way, the brightness/velocity phasing of star curves is correct and the doppler shifts are of the right order. So, even though a brightness curve might match perfectly and vary by 1.5 or so (linear), the actual spectral shift is diluted to only a very small fraction of that value. I'm wondering if there isn't a time dependent term in the 'compressibility equation'. Does a second order effect come into play? (da/dt) da/dt is the derivative of the acceleration. For a circular orbit, v = sin(wt) where w is the angular frequency or 2 pi / P where P is the orbital period. a = dv/dt = w cos(wt) da/dt - -w^2 sin(wt) It would come in as one more order than acceleration so would be roughly a factor of 1/P less than the basics we have discussed. For a one day orbit it would be four orders of magnitude smaller or make a change of about 0.01% to your curves, not worth worrying about. 'a' goes from -1 through zero to +1. The difference ratio can be infinite. You need to revise your calculus Henry. Well, that's the principle of ADoppler. The radial acceleration between two points on a circle varies with position. A short length will generally not ADoppler contract by the same relative amount as a larger one because the integrated acceleration is different across its ends. However I don't think this can explain the effect I am thinking about. so forget it. No, the speed difference is delta_v = a * t so the ratio of speed difference to time is linear. Only if a is constant.. No, a can vary in any way you like in which case delta_v is the integral of a.dt But lengths only ADoppler shift by the same proportion if they experience a CONSTANT acceleration. x___x' ----b y_____________________y' a1- Consider two identical guns that are accelerating towards the right at the same rate. When adjacent, they fire bullets at x and y respectively and then at y and y' after a certain time interval has elapsed. What do we know about the relative spacing between the bullets from each gun? 1) when da/dt= 0 2) when da/dt 0, as in the case of circular motion. Anyway let's not delve too deeply into this because I suspect there is a far more important factor involved. INDIVIDUAL PHOTONS simply do not compress as much as the groups do. When (if ever) you quantise ballistic theory, you will start by taking the wave theory result and showing that the quantum version produces identical results for large aggregates. Not so George. Nobody has the faintest idea about physical properties and structure of photons and this theory mighht provide a few clues.

One thing I would like to now is why a gamma particle can have such an obviously small 'cross section' compared with an RF signal. No current theory even goes close to explaining this George. I maintain that groups of photons behave differently from individual ones. The behaviour of groups is defined by the statistical formula that will form the basis of you method of quantisation. theories, theories........
