Here's a real fluke, look, a huff-puff star just happens to have a

What a strange coincidence, eh?
Perhaps the data was faked to make it look like a Keplerian orbit.

No, you just don't seem to understand that the velocity measured is
nothing to do with movement of the star as a whole for Cepheids.

You don't seem to have the faintest idea of what we're talking
about...not
that
Androcles does either.

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..

That seems a very peculiar thing to believe, given that we know that all
the
light we see at any time in the cycle has the same speed.

If you haven't anything more constructive to say, go away....you poor
indoctrinated fool....

OK, so how am I wrong? We DO know that all the light we see is coming
towards us with the same speed. Spectral lines demonstrate this.

You claim otherwise, justify your claim.
