Why are the 'Fixed Stars' so FIXED?

Either way, you get the same field. Smack dab in
the middle of the field is the white dwarf optical
counterpart to PSR J1909-3744. A most ordinary
looking image of a most ordinary looking star.
No swirling clouds of gases, no accretion disk...

Good....now can you provide me with its brightness curve?

Sure. The white dwarf has virtually constant brightness.

Evidence please....

As dead stars which do not support thermonuclear reactions,
white dwarf stars in general lack "heat engines" which would
support oscillatory pulsations such as might be exhibited by,
say, dwarf Cepheids.

theories, theories....

This is not to say that the surface of the white dwarf companion
of PSR J1909-3744 is non-turbulent. Far from it. Tidal effects
from the closely orbiting pulsar would be expected to drive
complex "weather" patterns on its surface. However, any
luminosity variances due to these effects would be completely
negligible relative to the flux of black body radiation.

The pulsar isn't orbiting the star...it barely moves.

The rate of mass transfer from white dwarf to pulsar which in
the distant past resulted in the speedup of the pulsar's rotation
rate to its current 340 Hz has dropped to negligible levels.
Currently, there is virtually no contribution to the measured
luminosity from any accretion disk on the pulsar.

theories, theories...
Are you saying that the dwarf's axis of rotation is the same as that of the
pulsar?


Why are you so focused on the white dwarf companion? The major
focus of observations on this and other orbiting pulsars is
on the pulsar itself.

If I know its brightness curve I can tell you a lot more about the whole
complex...according to BaTh.

What brightness variations does BaTh predict for the pulsar at
radio frequencies? Have these brightness variations ever been
observed?

My term 'brightness variations' means 'pulse bunching' in the case of pulsars.
However, I would be interested to know if every second pulsar pulse was
slightly different. One would expect two pulses every rotation would one not?



Like what?

If you knew anything about physics you wouldn't ask questions
like that.


Being evasive means that you don't have an answer.

Well please tell me how a magnetic field can escape a neutron star when light
cannot....




Yes, OF COURSE the Shapiro effect is a consequence
of lensing!

hahahhohoho!

So you agree that the Shapiro effect is responsible
for the measured shape. At least you've agreed on
SOMETHING.

Now go match it with your program.

It is some kind of physical effect not covered by my program.
..nor is it supposed to be.

In other words, your program is incapable of explaining the
Shapiro delay.

Even though you previously said it would...

It can produce a dip or a peak very similar to the type of effect you are
calling 'Shapiro delay'.

Since everything written about pulsars is likely to be completely wrong, how
can I comment.



So back to your program, what parameters do you get
for the orbit and maximum extinction distance if you
match the velocity curve _including_ the phase?

I'm not ready to provide those figures yet.
but for a pulsar the velocity phase should
generally be the same as my 'brightness phase'
if some eccentricity exists.

Fine. Provide the figures. Until you do so,
consider your theory a failure.

..why don't you go and empty a few bedpans......


It all boils down to this:

Your program consistently fails to fit the measured data, whether
it be from orbiting millisecond pulsars or Cepheid variables.

After considerable debugging with George Dishman's help, your
program is considered to represent an accurate implementation of
Ritzian theory modified to take into account extinction effects.

My program didn't need George's help.
George is confused about VDoppler.

Since your program fails to predict important features of these
stars, BaTh is falsified.

Those 'important features' are mainly 'wrong interpretations of willusions'.

Good job!

Back to studying..

Have you learnt how to turn the patients over yet?
