Bz, there is a very simple reason for that.
No telescope can resolve them because they only occur at very large distances.
DeSitter's arguments concerning several close binaries were shown to be wrong.

Predictions are that fluctuations are reduced in size as distance is increased.

That kind of 'double peak' curve is actually quite common.
There is a category named 'flare stars'. These are observed to emit a bright
flash periodically. Many emit a double flash.
The BaT provides the reason for this.

I don't think I iincluded that in the source I sent you. You might have to look
up the one on the website.

This is the principle:
Photons that are emitted during the 'concave' section of an orbit tend to bunch
together as they travel through space. Thus all the information occuring in
half an orbit period will arrive at an observer over a much shorter time span.
For instance, if a binary pair is itself in a larger orbit around a third
object, all the information from the larger half orbit can be compressed into a
much shorter time. Thus the binary period might appear to be much storter than
it actually is.

I wouldn't agree.
The BaT is a much better indicator of yaw angle than current methods.
If maximum peripheral velocity can be ascertained using doppler, the BaT can
reveal almost everything one wants to know.

All stars are in some kind of orbit around another star or larger body.

My suggestion is that one hot and one cool star in a more eccentric orbit
around each other would both experience large tidal effects when they were
close. That could cause the stars to periodically appear larger and smaller,
depending on the observer's position..

Whatever you say about density will never result in a dead constant frequency

Einstein's SR theory is just LET in disguise.

But the other star is about 60degrees around the orbit, I think.

The BaT predicted brightness curves would be rather complex. As well as there
being three bodies, there would be an unusual phase relationship between the
curves..

If a 'speed' is not defined relative to something, then it is NOT A SPEED.

Let's think about that.

The absorption line wavelengths are acurately known.
If both the absorption lines and the spectrum is doppler shifted, what
conclusions can we reach?
If a spectrum is doppler shifted but the absorption lines ARE NOT, what
conclusions can we reach?
If an absorption line is doppler shifted, but the spectrum is not, what
conclusions can we reach?

that would be true except for the fact that the observed brightness might be

No it isn't.
The companion stars are WCHs.... Very heavy..

it is.

Don't be ridiculous.

Paul, I know from their light curves that the eccentricity of their orbits is
between about 2 and 4.

Do you not agree that tidal effects would be enormous when two heavy stars
moved very close to each other at the perihelion.
Maybe they would only be a few diameters away from each other.
What strange shapes might a ball of gas take on?

You can scream and rave as much as you like but at least this mechanism would
explain the dead constant period. Huffing and puffing certainly cannot.

Why do you keep talking about eclipsing binaries, Ghost.
They have nothing whatsoever to do with our subject.
Most binaries do NOT eclipse.

D Cep has been constant to within a second for twenty years. Its brightness

All stars eventualy run out of gas.
Cephids dont really huff and puff, Ghost. They are perfectly stable like our

They reckon the observed doppler shift is in line with the huffing and puffing,
Ghost. But it is actually lags by about 30 degrees, just as the BaT would
predict.
THEY fabricate He and H ionisation layers to try to explain the phase lag. :)

So prominances prove that standing acoustic waves
can't exist in stars.

Not very, though.

Quite.
All you have to do to prove that Cepheids cannot be
pulsating stars is to call them "huffing and puffing". :-)

You are really doing well now, Henri. :-)

YOU invoked multiple images as the cause of the curves making little sense.

I predict that at any distance greater than 10 wave lengths, BaT will

BaT provides a reason for everything except why some things are not
observed more often and why superluminal/subluminal photons have never been
observed.

Get actual data points and plot them. Fit a curve to them.
Look at the estimated error.
'Dead on' is not the way I would describe the period.

Very slow. On the order of hundreds of thousands of years.

I have several different versions I have downloaded from the website at
different times, in addition to the code you sent me.

NONE have a time compression button. If you give me a clue as to where you
want me to look, I will be glad to look at it.

You had your yaw angles off by a large factor due to inverting the
brightness data.

Even after correcting that, I predict that your guesses at yaw angles will
be no better than chance predictions of yaw angles.

Only your very strong faith could have mistaken any yaw angles you derived,
with inverted brightness curves, for correct information.

The fact that you were taking slow rise, rapid fall curves for confirmation
of rapid rise, slow fall data should cause you to stop, throw out
everything you have been thinking about BaT, and start over again.

It didn't. That shows that faith is governing your thinking, not scientific
thought.

The center of their galaxy, at least. So what?

You are handwaving in order to hold onto your faith. You have been
attempting to support your theory that all cepheid variables are due to
binary star systems or single stars with eccentric orbits.

Many such binaries have been observed.

They do not look like cepheid. They show dual doppler shifts.

As one star receeds, its light is redshifted. Meanwhile the other star
approaches and its light is blue shifted.

This is clear, even when the stars can not be visually separated.

It does not look like a typical cepheid.

It does not look like a typical cepheid.

It does not look like a typical cepheid.

You said "It definitely does not look like a sine wave when an elliptical
orbit is used. It looks just like the typical cepheid one.

The typical cepheid is a sawtooth with fast increase, slow decline in
brightness.

Your program's predictions do not match what is seen in the heavens.

Why bother? Your faith is strong. You won't look at anything that

Faith is not required. Useful results is all that science requires. The HR
diagram gives useful results.

You still don't understand that science is always questioning. It is NOT
based on faith.

In the 3 body, LaGrange situation, there are 5 LaGrange points. Some are
stable points, some are not.

Einstein has the advantage of often having been tried, but never denied by

There have been thousands of attempts to refute c as a constant.
ALL have failed.

The possible k for c'=c+kv has gotten smaller and smaller.

It takes very strong faith to turn a lack of evidence into evidence.

The speed of photons is c wrt all observers. No exceptions have ever been
