Perhaps Henri will reconsider in the future, I hope so. Not a chance. Gawd! Another brainwashed fool. How does a pulse from an orbiting pulsar know how to travel to little planet Earth at the same speed as one emited 180 dgrees before? You see Paul? Henry knows that SR says the pulse also travels at c relative to the centre of the galaxy and the Andromeda galaxy and in every other inertial frame yet he deliberately pretends he is ignorant of that in order to pretend that it means Earth is in some way special just so he can be insulting George, remove the Earth and everything else from the universe. Your stupid rehashed aether theory says that all the pulses emitted by the orbiting pulsar will remain in a fixed spatial relationship with EACH OTHER as they traverse space. In other words, they are traveling at the same speed to wherever they are going. Yes, that's what the observations say they do. You are claiming that as each pulse is emitted, its speed becomes magically adjusted to exactly that of all the previous ones. Nope, and you know pefectly well that's a load of crap Henry, you've been told what SR says far too many times over the years. You are just inventing yet another deliberate distortion to hide from reality. I ask, are the fairies involved?...or do you still insist that space has absolute qualities? Your assessment of his approach is entirely correct, but since he knows I'm just helping him speed up his software and get the predictions to be correct for ballistic theory, I'm not a threat and he can hold the conversation. Why he got defensive when I pointed out he could use the Shapiro delay to determine the phase is a bit of a mystery to me. George, your method is not good for elliptical orbits or for adding the brightness contributions of a pair. It requires at least eight more arrays and is likely to cause gaps in the output curve. Well obviously you need to sort out the details. You described the method you were using and I pointed out some details you had missed that needed fixing. The way I would have written the software would have allowed the method I suggested to work but there's as many styles of writing as there are programmers so you have to fix it your way. It is one helluva thing to program compared with MY slightly slower but very acccurate method.. Speed isn't the key part, remember you said there was no phase shift for zero distance where the VDoppler should dominate so clearly you had a fundamental error. We need to know the phase so your program was unusable at that point. The reason George perseveres with me is that he knows I'm right. Nah, I just got fed up seeing you claim to have matched various Cepheid curves when your software obviously contained the same mistake as Sekerin so gave incorrect results and in fact ballistic theory can't match them at all. Oh rubbish George, The curves are accurate to 1 part in c/v. I can make them dead accurate but why bother... That accuracy would be fine, but you had a 90 degree phase error which is not acceptable. ...but he cannot let himself accept the fact that his whole belief system is wrong...so he is going down fighting. He wont even comment on this: http://www.users.bigpond.com/hewn/psr1913+16.jpg A perfect match to GR of course, but not much use for your purposes since there is no brightness curve (there is no variation) and there is no way to determine true phase. George, the published 'pulse bunching' curve was used by misguided astrophysicists to determine the velocity curve USING CLASSICAL DOPPLER EQUATIONS. I think they would be using the GR equations Henry. They don't apply...and the figures, upon which the rest of the theory is based, are completely wrong. The theory was written in 1917 Henry, it wasn't based on Hulse and taylor's figures, and the observations exactly match that theory. Yous eem to be getting confused with the Ritzian analysis which would be quite different. The observed bunching is that produced by a pulsar in CIRCULAR orbit, not an elliptical one....as the confused astronomers believe.. ... Henry still has to explain how the periastron of a circular orbit can advance ;-) George, I told you how that can appear to happen. Let me give you a hint Henry, circular orbits don't have a periastron. It is all to do with the way the pulses are created. The neutron star has around it a mass of swirling gasses, shaped into a thin dick, somewhat like the rings of Saturn... only lumpy and sufficiently irregular to cause the star to move in a small orbit. As the star spins, its magnetic field cuts the disk and initiates a bright pulse of mainly H spectrum light from certain parts of he disk. ... Utter rubbish Henry, the pulse is seen in the radio frequencies below microwave and is a broad band signal, the signals couldn't pulse as fast as they do because the heated gas would cool slowly and the radiation from the disc would be nearly omni-directonal other than some shadowing by other parts of the disc and the star. The precession of the disk matter may give the impression of a small movement of periastron...or the effect you claim might be nothing more than a beat between the orbit period and the pulsar spin rate. There are endless possibilities. Maybe, but you don't have the faitest idea how to come up with an alternative that actually explains what we see. So George, if you actually would succeed at some point to make Henri abandon his bath light theory, don't expect him to be grateful afterwards... Don't worry, Henry is incapable of that, he has painted himself into a corner. If he could change his mind, the Sagnac proof which he agreed would have been adequate. YOUR 'sagnac analysis' did nothing more than epitomise the stupidity of trying to use rotating frames of reference. Sixth time now Henry, the analysis you agreed was in the non-rotating frame. Your denial is getting severe, try to calm down a bit. My MO is simpler, I take the approach that good science must be able to prove itself so all I have been doing is a peer review of his software to get the bugs out and some digging to see if we can find observational data to match. Whether Ritzian theory can model that data or not is something I leave to the whim of the gods, all I expect is that the model should be accurately based on the theory. I think Henry (or whoever) is reasonably in touch with what the theory implies now and his program is probably getting quite accurate but I don't think he has fully grasped the use of residuals in determining whether he has a match or not. One day perhaps .... Your problem is that you accept the 'data'....when it is completely wrong. I accept_observations_ which in science are taken as the driving force. If your theory doesn't match, you discard the theory, not the observations. It is the interpretations of the observations that produce the wrong data. No Henry data are the observatory records on which the interpretations are based. For instance using VDoppler equations to analyse ADoppler bunching of poulasar pulses. Except that ADoppler gives a phase error, that's why the Shapiro effect is important. We observe the Shapiro effect to coincide with a point of negligible Doppler shift, you want it to be 90 degrees away from where we see it sonow you have stopped talking about the science and started getting abusive instead. Maybe that's a sign that you know subconciously that your claims are unsupportable but I'll give you the benefit of the doubt and wait to see if you can return to the technical discussion. George. I'm not particularly interested in whether or not a Shapiro effect exists because it makes no difference to what my program achieves.. Of course it does Henry, you have to match the phase and Shapiro tells you that ..the BaTh matching of just about any star curve...and pulsar 'velocity curve'.... Other than your 90 degree phase error of course. George |

Rotating one's head is irrelevant. The rotation that you describe (A "roll" of either the head or the projected ellipse) simply puts the long axis of the projected ellipse on the viewer's X axis. That is convienient but has no effect on the process of multiplying radial velocities and accelerations around the orbit by a factor of cos(pitch). You said this previously and I do not understand why George did not point out its irrelevancy at that time. Do I understand your terminology correctly as saying that the "pitch" of an orbit is zero when seen edge-on and 90 degrees when seen face-on? If so, your term "pitch" means the same as "inclination", which is the term everyone else uses in astronomy. Though it is often measured as angular deviation from face-on rather than from edge-on. That is how it is used in arXiv astro-ph/0507420.pdf (Table 1, "Orbital inclination, i") To double-check that we are talking about the same thing, see the illustration of "yaw", "pitch", and "roll" near the top of this page: Leonard, I think Henry has just swapped some definitions for convenience. His cos(pitch) is the same as the usual sin(inclination). I'm less clear about his yaw but I'm fairly sure it is directly related to the longitude of the ascending node. George |

Whether or not cepheids are really huff-puff stars doesn't matter. We say their brightness variations are due to c+v effects caused by their surfaces moving in and out. A brightess curve produced that way is likely to be similar to that for a star in elliptical orbit. What ????? For years you have been saying that Cepheids were plain constant-luminosity stars and the variation was due to c+v effects because they are in binary systems that have not been recognised as such. No I changed that opinion some time ago George. I accepted that the presence of harmonics in the brightness curves was pretty hard to explain on purely 'orbit' grounds. So it is quite likely that two factors are contributing to the brightness curves of these stars. Their orbit motion and the huff-puffing of their surfaces. Given that you now accept the huff-puff nature, you need to reconsider your justification for saying that Cepheids that are currently thought of as isolated might actually be part of a binary. If you are now switching to say they are single stars, why on Earth would your software be modelling binary systems and restricting the solutions to Keplerian orbits when the motion of the surface is due to internal pressure? I think it is my turn to say you are getting very confused Henry. It is a fact that most 'cepheids' appear to have a companion... It is a fact that something around half of _all_ stars are in binary systems so there is no reason why Cepheids should be an exception. which means they are in some kind of orbit. I reckon the movement of their surfaces would feature similar radial velocities to those of an orbit. It is distinctly possible that the huffing is linked to the orbit period. It is also possible that the stars are in tidal lock .. It is certainly possible, especially for close binaries, but less likely for those with greater separations. and distorted into some kind of dumbell shape, No, each would be more like an egg shape. Look up "Roche Lobe". leading to a brightness variation as they orbit....but that wouldn't account for the short periods of many of them. It wouldn't account for any where the period of the Cepheid differs from the orbital period, nor does it account for those that are not in binary systems. George |

We know the pulsar produces pulses regularly every 2.285ms and it doesn't matter whether that is one or two or 27 per rotation, all that matters is that we can measure that they are emitted with a regularity almost as good as an atomic clock. I was under the imp[ression that the observed pulse was slowly changing too. Not to worry... Pulsars are normally slowing very slightly but it is _very_ gradual: http://outreach.atnf.csiro.au/educat...ryone/pulsars/ "For example, a pulsar called PSR J1603-7202 is known to have a period of 0.0148419520154668 seconds. However the periods of all radio pulsars are increasing extremely slowly. The period of PSR J1603-7202 increases by just 0.0000005 seconds every million years!" Not quite, you are jumping ahead and making the mistake you accuse me of. What we know is the _TDoppler_ factor. Orbital velocity has to be determined from that and other information using your software. The VDoppler contribution is negligible...forget it. Nope, the simple indication from the phase is that it is completely dominant. If you want to forget it you have to show an alternative model, such as a higher eccentricity, that explains the phase. I'm not saying you can't, only that you cannot just wave your hands and pretend the phase data doesn't exist. If you read what I said in tyhe other message you will now know that the VDoppler effect doesn't exist...as I originally thought. We have since corrected that, your new numbers are realistic. We know the latter is much smaller than our true distance so you can treat the observer as being at infinity and the distance is then that of the speed equalisation only (the curves are asymptotic to those at infinity and within 0.1% at 7 times the equalisation distance). I understand you point. There are two options. There are at least three. You are concentrating on one.. No, what I tried to do was walk you through each option in turn, first low orbital velocity, then high inclination and finally speed equalisation. ..that which incorporates a large degree of speed unification. ..and VDoppler is dominant at small distances. I am now leaning towards a much lower rate of unification and a very small orbit diameter and speed. OK, but the phase may be wrong unless you can compensate in some other way and you will probably get a value for the stellar masses that is not tenable. I think you'll need the speed unification but working through the alternatives is the best way to understand why so carry on and I'll see if I can ask the awkward questions. I'll let you absorb what I have said above before I continue this... Time to continue then. For J1909-3744 we know from the Shpiro delay (or the side effect of gravitational lensing if you like) that we see the orbit close to edge on and that the velocity curve has a phase that corresponds to purely VDoppler for a near circular orbit. You tell me what your program parameters need to be to match that curve. I don't agree that the effect to which you refer is an indication that the orbit is nearly edge on... In that case you would need to give an alternative explanation for the pulse delay and explain why that effect is not seen in other tests. George, I am questioning the very way pulses are created. I don't really care about that, I want to know why they are delayed after they have been created. Are they delayed or advanced? Ballistic theory says they should be advanced but they are actually delayed. All we have is a theory. It might be completely wrong. How do YOU explain the existence of pulses. The source emits a beam and spins like a lighthouse, you know that already. I don't know that any more. I dont think that explains what is observed. Do you think the beam is a narrowly focussed 'pencil'... or is it a plane? See the illustration here http://outreach.atnf.csiro.au/educat...ryone/pulsars/ In one of the papers I cited some time ago, there was a diagram shoing a cross-section where precession means we have stripes across the beam, like the scan lines of a TV. The shape exactly matches the known effect seen many ways in the Solar System as Leonard listed so your rejection of it is neither credible nor understandable. I could understand if you objected to the Shapiro effect in general since it's the wrong way for ballistic theory but I am not arguing that. George, GR and the BaTh have the same equations as regards the slowing of light or the distortion of space to maintain its speed at c. No they don't Henry, nothing like it. George, the BaTh says light speed increases when light falls down a gravitty wwell just like anyhting else does. Yes, so the signals from the pulsar when it is on the far side of the companion should be accelerated towards us and then slowed to the original speed once it has passed the dwarf and is en route to us. That would produce an advance of the arrival time as we discussed some time ago. You appeared to agree the mechanism then so can you go back and have another read, I don't want to write all the same stuff again. GR effectively says the light s[p]eed remains constant and SPACE contracts to make that so. As the Pound- Rebka experiment showed, both approaches give the same answer. Pound-Rebka showed that processes seem to go slower when viewed from a higher potential. In GR the light seems to move slower when it is close to the companion hence it predicts a delay. If there IS a Shapiro effect then both theries should agree. They don't, we worked through ballistic theory some time ago and you eventually agreed that it predicted an advance instead of a delay. Don't you remember? You left out a '-'. The effects should be the same. Go back and read it, there were no equation, just a simple (hough slighly ambiguous) diagram which I clarified when you and Jeff both queried it. Forget it Henry, we see a white dwarf where one is expected and you couldn't get anything like the right spectrum or intensity any other way. We see a bright dot in the sky George. It could be anything. No Henry, it could not "be anything", it is a white dwarf because it has the spectrum that falls into that classification. For an edge-on low velocity model, you will get a mass for the pulsar which is of the order of millions of solar masses (caveat: mental arithmetic), at (or a bit below) the bottom end of the 'super-massive black hole' category and that can be ruled out by the lack of gravitational disruption of nearby stars. You're not thinking rationally any more George. Back to the abuse Henry? I'm just applying Kepler's laws and you say your program uses them so it should agree. Well you got the VDoppler business wrong for a start... Strange how you now agree with me. ..just starting to rave like the rest... Try cleansing your mind of just about everything you ever learnt about astronomy. It is nearly ALL wrong. ROFL, so far all your program has done is prove it all correct, the phase means the TDoppler must be pure VDoppler which means all the standard results stand. there is NO VDoppler George. You know better now, my point stands. No, I'm telling you nothing more than what is obvious in the measurements. The light curve is flat over 358 degrees of the orbit and goes to zero for 2 degrees. There could easily be some kind of eclipse. Yes Henry, it isn't actually the other pulsar that blocks the view, it's too small. It's the opaque plasma (like the "solar wind") that eclipses the primary pulsar but the fact is that you only get an eclipse when the opaque material is in the line of sight, and that tells you the phase. Theories, theories...all based on wrong data... What is the truth? The truth is that the luminosity drops to near zero for 2 degrees of the orbit, that is the data and it is not an interpretation. There could easily be another explanation...for instance whatever the magnetic field reacts with has a dip in it. But the field rotates hundreds of times a second and the eclipse last 48 seconds every 2.4 hours (figures estimated from memory but right order of magnitude). But what is the form of the magnetic field? How can a magnetic field escape a neutron star when light cannot? Why do you say light cannot escape Henry, of course it escapes or we couldn't receive the pulses. Tough Henry, observations are what they are, you can produce alternative explanations but you cannot change reality. How we interpret wilusions from 4000LYs is wide open to error. Using constant c is the major source of that error. An eclipse isn't hard to interpret. Oh but it is. The Bath expects many orbiting stars to appear as though they are eclipsing. All that is required is a moderately eccentric orbit and a periastron approx. nearest to the observer. Go on then, show how your program produces a drop to zero luninosity, or say by just five or six magnitudes, for just two degrees of the orbit with no variation at any other time. That is what the program is for isn't it? George |

Rotating one's head is irrelevant. The rotation that you describe (A "roll" of either the head or the projected ellipse) simply puts the long axis of the projected ellipse on the viewer's X axis. That is convienient but has no effect on the process of multiplying radial velocities and accelerations around the orbit by a factor of cos(pitch). You said this previously and I do not understand why George did not point out its irrelevancy at that time. Do I understand your terminology correctly as saying that the "pitch" of an orbit is zero when seen edge-on and 90 degrees when seen face-on? If so, your term "pitch" means the same as "inclination", which is the term everyone else uses in astronomy. Though it is often measured as angular deviation from face-on rather than from edge-on. That is how it is used in arXiv astro-ph/0507420.pdf (Table 1, "Orbital inclination, i") To double-check that we are talking about the same thing, see the illustration of "yaw", "pitch", and "roll" near the top of this page: Leonard, I think Henry has just swapped some definitions for convenience. His cos(pitch) is the same as the usual sin(inclination). I'm less clear about his yaw but I'm fairly sure it is directly related to the longitude of the ascending node. It is the angle between the LOS and the major axis, in the edge on position. Any edge on orbit can be rotated about the axis perpendicular to the LOS. At any particular angle, all RADIAL velocities and accelerations will be multiplied by the same factor, my cos(pitch). ALL POSSIBLE ORBIT CONFIGURATIONS (WRT EARTH) CAN BE CREATED IN THIS WAY.

No I changed that opinion some time ago George. I accepted that the presence of harmonics in the brightness curves was pretty hard to explain on purely 'orbit' grounds. So it is quite likely that two factors are contributing to the brightness curves of these stars. Their orbit motion and the huff-puffing of their surfaces. Given that you now accept the huff-puff nature, you need to reconsider your justification for saying that Cepheids that are currently thought of as isolated might actually be part of a binary. Every one I read about seems to have a companion star. If you are now switching to say they are single stars, why on Earth would your software be modelling binary systems and restricting the solutions to Keplerian orbits when the motion of the surface is due to internal pressure? I think it is my turn to say you are getting very confused Henry. It is a fact that most 'cepheids' appear to have a companion... It is a fact that something around half of _all_ stars are in binary systems so there is no reason why Cepheids should be an exception. ....all stars are obiting some kind of mass centre. which means they are in some kind of orbit. I reckon the movement of their surfaces would feature similar radial velocities to those of an orbit. It is distinctly possible that the huffing is linked to the orbit period. It is also possible that the stars are in tidal lock .. It is certainly possible, especially for close binaries, but less likely for those with greater separations. and distorted into some kind of dumbell shape, No, each would be more like an egg shape. Look up "Roche Lobe". Yes, egg shaped...that would cause a brightness variation at double the orbit frequency. leading to a brightness variation as they orbit....but that wouldn't account for the short periods of many of them. It wouldn't account for any where the period of the Cepheid differs from the orbital period, nor does it account for those that are not in binary systems. That is true. That's why I accept the possibility. However it doesn't make any difference to the fact that the brightness variation of huff-puff stars conforms with BaTh. In every paper I have read about cepheids, the authors admit the have no theory to link the surface movement to the brightness curve.

We know the pulsar produces pulses regularly every 2.285ms and it doesn't matter whether that is one or two or 27 per rotation, all that matters is that we can measure that they are emitted with a regularity almost as good as an atomic clock. I was under the imp[ression that the observed pulse was slowly changing too. Not to worry... Pulsars are normally slowing very slightly but it is _very_ gradual: http://outreach.atnf.csiro.au/educat...ryone/pulsars/ "For example, a pulsar called PSR J1603-7202 is known to have a period of 0.0148419520154668 seconds. However the periods of all radio pulsars are increasing extremely slowly. The period of PSR J1603-7202 increases by just 0.0000005 seconds every million years!" ...which is exactly what the BaTh predicts for a pulsar that is in a very large orbit. ..but it is also to be expected that they should be slowing as they lose energy. I see no problem there. The VDoppler contribution is negligible...forget it. Nope, the simple indication from the phase is that it is completely dominant. If you want to forget it you have to show an alternative model, such as a higher eccentricity, that explains the phase. I'm not saying you can't, only that you cannot just wave your hands and pretend the phase data doesn't exist. If you read what I said in tyhe other message you will now know that the VDoppler effect doesn't exist...as I originally thought. We have since corrected that, your new numbers are realistic. The 'correction' is negligible. We know the latter is much smaller than our true distance so you can treat the observer as being at infinity and the distance is then that of the speed equalisation only (the curves are asymptotic to those at infinity and within 0.1% at 7 times the equalisation distance). I understand you point. There are two options. There are at least three. You are concentrating on one.. No, what I tried to do was walk you through each option in turn, first low orbital velocity, then high inclination and finally speed equalisation. ..that which incorporates a large degree of speed unification. ..and VDoppler is dominant at small distances. I am now leaning towards a much lower rate of unification and a very small orbit diameter and speed. OK, but the phase may be wrong unless you can compensate in some other way and you will probably get a value for the stellar masses that is not tenable. I think you'll need the speed unification but working through the alternatives is the best way to understand why so carry on and I'll see if I can ask the awkward questions. I'll let you absorb what I have said above before I continue this... Time to continue then. For J1909-3744 we know from the Shpiro delay (or the side effect of gravitational lensing if you like) that we see the orbit close to edge on and that the velocity curve has a phase that corresponds to purely VDoppler for a near circular orbit. You tell me what your program parameters need to be to match that curve. I don't agree that the effect to which you refer is an indication that the orbit is nearly edge on... In that case you would need to give an alternative explanation for the pulse delay and explain why that effect is not seen in other tests. George, I am questioning the very way pulses are created. I don't really care about that, I want to know why they are delayed after they have been created. Are they delayed or advanced? Ballistic theory says they should be advanced but they are actually delayed. No. The BaTh should be in agreement with GR. All we have is a theory. It might be completely wrong. How do YOU explain the existence of pulses. The source emits a beam and spins like a lighthouse, you know that already. I don't know that any more. I dont think that explains what is observed. Do you think the beam is a narrowly focussed 'pencil'... or is it a plane? See the illustration here http://outreach.atnf.csiro.au/educat...ryone/pulsars/ In one of the papers I cited some time ago, there was a diagram shoing a cross-section where precession means we have stripes across the beam, like the scan lines of a TV. It's a pretty crappy article. Quote: "The time between pulses, the period, is the time that it takes for the neutron star to rotate once. " Why aren't two pulses emitted per rotation? and: "Therefore the most likely explanation is that a pulsar is a neutron star that spins rapidly and emits radio waves along its magnetic axis. However, not all neutron stars are necessarily detectable as pulsars. The beams from some neutron stars may never pass the Earth and will therefore not be detected. Also, other neutron stars may have been pulsars in the past, but the process that causes the beam of radiation (which is not fully understood) may have turned off or is just too weak to be detected. " In other words, they don't know. George, GR and the BaTh have the same equations as regards the slowing of light or the distortion of space to maintain its speed at c. No they don't Henry, nothing like it. George, the BaTh says light speed increases when light falls down a gravitty wwell just like anyhting else does. Yes, so the signals from the pulsar when it is on the far side of the companion should be accelerated towards us and then slowed to the original speed once it has passed the dwarf and is en route to us. That would produce an advance of the arrival time as we discussed some time ago. You appeared to agree the mechanism then so can you go back and have another read, I don't want to write all the same stuff again. GR says the same. GR effectively says the light s[p]eed remains constant and SPACE contracts to make that so. As the Pound- Rebka experiment showed, both approaches give the same answer. Pound-Rebka showed that processes seem to go slower when viewed from a higher potential. In GR the light seems to move slower when it is close to the companion hence it predicts a delay. But the companion is orbiting the star....not vice versa... The pulsar is barely moving. If there IS a Shapiro effect then both theries should agree. They don't, we worked through ballistic theory some time ago and you eventually agreed that it predicted an advance instead of a delay. Don't you remember? You left out a '-'. The effects should be the same. Go back and read it, there were no equation, just a simple (hough slighly ambiguous) diagram which I clarified when you and Jeff both queried it. Forget it Henry, we see a white dwarf where one is expected and you couldn't get anything like the right spectrum or intensity any other way. We see a bright dot in the sky George. It could be anything. No Henry, it could not "be anything", it is a white dwarf because it has the spectrum that falls into that classification. Well if it can be positively identified let''s see its brightness curve. Do you think we can ask someone to try to measure it for us? Are you in touch with any astronomers? Back to the abuse Henry? I'm just applying Kepler's laws and you say your program uses them so it should agree. Well you got the VDoppler business wrong for a start... Strange how you now agree with me. I agree ..but it is a negligible effect .....and not related to extinction. ..just starting to rave like the rest... Try cleansing your mind of just about everything you ever learnt about astronomy. It is nearly ALL wrong. ROFL, so far all your program has done is prove it all correct, the phase means the TDoppler must be pure VDoppler which means all the standard results stand. there is NO VDoppler George. You know better now, my point stands. it is a negligible effect .....and not related to extinction. No, I'm telling you nothing more than what is obvious in the measurements. The light curve is flat over 358 degrees of the orbit and goes to zero for 2 degrees. There could easily be some kind of eclipse. Yes Henry, it isn't actually the other pulsar that blocks the view, it's too small. It's the opaque plasma (like the "solar wind") that eclipses the primary pulsar but the fact is that you only get an eclipse when the opaque material is in the line of sight, and that tells you the phase. Theories, theories...all based on wrong data... What is the truth? The truth is that the luminosity drops to near zero for 2 degrees of the orbit, that is the data and it is not an interpretation. eclipses CAN occur. ....but there can also be eclipse-like dips in brightness curves caused purely by c+v. But the field rotates hundreds of times a second and the eclipse last 48 seconds every 2.4 hours (figures estimated from memory but right order of magnitude). But what is the form of the magnetic field? How can a magnetic field escape a neutron star when light cannot? Why do you say light cannot escape Henry, of course it escapes or we couldn't receive the pulses. I was under the impression that no light can escape from the neutron star itself. An eclipse isn't hard to interpret. Oh but it is. The Bath expects many orbiting stars to appear as though they are eclipsing. All that is required is a moderately eccentric orbit and a periastron approx. nearest to the observer. Go on then, show how your program produces a drop to zero luninosity, or say by just five or six magnitudes, for just two degrees of the orbit with no variation at any other time. That is what the program is for isn't it? Sure. www.users.bigpond.com/hewn/narrow.jpg George Einstein's Relativity - the greatest HOAX since jesus christ's mother. |
