You attempted without success to sidetrack the issue
from one which was absolutely, totally fatal to the
BaT/c+v theory of Cepheid light variability.

Run away, you pathetic, whining loser. Hide your head
in the sand and issue one of your famous plonks.
You plonked my brother two or three times as I recall.

The challenge remains:
Please explain RU Cam in terms of BaT / c+v theory

AAVSO Photoelectric Observations of RU Cam
John R. Percy and Yvonne Tang
RU Cam is a population II Cepheid which "stopped pulsating"
in 1965-66. Actually, it did not stop pulsating completely;
the amplitude decreased from over a magnitude to about 0.20,
and remained stable at that level from 1967 to 1982,
according to the work of Bela Szeidl and his colleagues.
The period has fluctuated erratically between 17.4 and 26.6
days, but this may be the result of random, cycle-to-cycle
fluctuations. As noted below, the HIPPARCOS satellite found
a mean period and amplitude of 22.24 days and 0.20 magmitude,
during its 3.5-year mission.

I'm right and you are wrong, you are too chicken to address real data
and you can't explain RU Cam in term of
of c constant theory.

Hey, loser! Can't you read? The problem of RU Cam is
one of stellar evolution, not relativity. Theory
indicates that Cepheids pulsation is a temporary
phenomenon. As a star ages, it may cross a part of the
HR diagram where its outer layers become unstable.
Energy trying to escape from the star is absorbed by
cool material near the surface, causing the star to
expand. The blocking layer thins, allows energy to
escape, and the star cools and contracts. In a few
hundred thousand years, as the star ages, it exits
this region of the HR diagram and is no longer a
Cepheid.

It is you and Henri, on the other hand, who want
to explain Cepheids in terms of c+v theory.

Jerry, the ballistic theory of light (BaT) fully explains the phenomena you
claim brings its downfall.

If you care to study my Vbasic program:
www.users.bigpond.com/hewn/variablestars.exe
you will learn how the predicted brightness curves are very much
'observer-distance' dependent. There are many factors other than direct
intrinsic changes that might affect the varying appearance of a star.

Eclipsing binaries, for instance, might NOT all be just that. The BaT shows
that stars in moderately eccentric orbits with their perihelions closest to
observer will exhibit the same type of brightness variation.... Algol type
stars.

RU Cam is probably a ternary system, which would account for any period
irregularity. Alternatively, it is a binary pair that is itself in orbit around
another large mass. Under certain conditions, that situation can cause 'time
compression' of observed information. Hence, the observed period can appear to
change steadily over a long period when in fact it is quite stable. Its
variation faded away simply because the star moved well aweay from the critical
observer distance.

Your problem is that you have never even tried to consider the full
rammifications of the fact that the Earth is not the centre of the universe.
All the starlight in the universe WAS NOT emitted, godlike, at exactly c wrt
little planet Earth.
Light is emitted at c wrt its source. It has no other reference.

You rant and rave about how the BaT DOESN'T explain this or that when you don't
know the first thing about the subject and haven't even bothered to find out
more.

My variablestar program is undergoing improvements at present but will still
tell you a great deal about the BaT.

"Delta Cep is one of the few easily-visible variables, its magnitude changing
from 3.5 to 4.3 and back over an amazingly regular period of 5 days 8 hours 47
minutes and 32 seconds, the star acting like a natural clock. "
