IF.....??

The K and V curves are those of light emitted by a surface moving with the
radial velocities of Keplerian orbits. Both curves differ in 'yaw angle' and
'eccentricity', which in the case of a huffpuff, indicate the hysteresis in the
movement and the different characteristics between the in and out movements.
The ~80 degree phase difference shows that the two bands originate from
different layers at different times.

You are trying to make the circularity you are accusing me of,
namely starting with the K- and V-light curves, and trying to
guess what the parameters in your model must be to predict
the observed observed data.

But despite of this circularity, you do not succeed.
There simply IS no way your model can produce the observed
data.

I have already produced the curves and the REAL data required to produce them.

If you still haven't fathomed that, you better read again
my original posting where I prove the above to be facts.

Naturally the three willusions are consistent with each other since they are
caused by the same factors.

As the primary, measured data, I will use the temperature in fig. 4.3 in:
http://ses.library.usyd.edu.au/bitst....0014whole.pdf

Note that the temperature curve is inferred by
the absorption lines - and defenitely NOT by
the measurements

....what measurements?

and the radius curve in fig 3 in:
http://www.arxiv.org/PS_cache/astro-.../0402244v1.pdf

yes....all wrong.....
......very sad really to see so much effort wasted because of Einstein.

Note that radius curve is confirmed by spectroscopic
measurement, which is a very direct method of measuring
the diameter.



This means that the input data do not depend on
measurements of the black body spectrum!

It depends on constant light speed.

The question is:
What will the K (2.2u) and V (0.5u) light curves be
according to Planck's blackbody radiation law?

The result is shown in the table below. Here a
Int = the surface radiation intensity relative to the intensity at phase 0.
Lum = the luminosity (intensity*area) relative to the luminosity at phase 0.
Mag = the magnitude relative to the magnitude at phase 0.

The Intensity is calculated from Planck's black body radiation law.
Planck(T,lambda). (Look it up if you don't know it.)

It's in my physics book. Would you like a copy?

K Int = Planck(T,2.2u)/Planck(5600,2.2u)

The fit is good simply because Planck's black body radiation law
is correct, and a Cepheid is what it is known to be - a pulsating star.

Whether or not it is pulsating is not important. Its luminosity variation is
due primarily to cyclical changes in c+v.....as is the case for most variable
stars.

This is an indisptable FACT, Henri:
The K and V light curves from l Carinae are exactly as
Planck's law predicts them to be if the star is
a pulsating star with temperature curve and diameter curve
as measured.

Paul, Planck's Law says nothing about variations in a star's luminosity.

I don't believe in coincidences.
So when
The K and V light curves from l Carinae are exactly as
Planck's law predicts them to be if the star is
a pulsating star with temperature curve and diameter curve
as measured.
it is because
l Carinae is a pulsating star with temperature curve and
diameter curve as measured.

Even if L Car does happen to pulsate a little..and that's debatable...most of
its lumnosity variation is due to ADoppler..derived from variable light speed.
This is proved by the fact that I can match the K and V curves exactly using
nothing but BaTh.
