Why are the 'Fixed Stars' so FIXED?

However my program IS strictly limited to Keplerian orbits. I introduced
the
phase variation to investigate Lagrange points....and found evidence that
objects DO exist at the 60 degree one.

How can YOU explain a curve like this one:

It's certainly not a simple overtone.

..but the dip can be explained with an object rotating in the same orbit but
with 60 degree lag.

see S Cas in:

Mine is the yellow curve....a perfect fit...

Unfortunately, however, I cannot explain the claimed magnitude change of about
9. In fact I don't believe it. According to the britastro website, there is a
group of stars that appears to have very large changes in brightness. How do
YOU explain those? I think somebody forgot to convert to a log scale.



What mass ratio?

You can get an estimate from the relative sizes of the dip and main curve. I
would say about 4:1 .

Actually, to produce that kind of curve, the velocities of the two objects have
to be the same.... but one is about 0.4 as bright as the other. The phase
difference is 60.
