Paul Andersen referred me to this site:

Incidentally, Algol supposedly eclipses for 10 hours every 70 hours.
That means one star is occulted by the other for 52 = 360 * 10/70
degrees
and that the smaller can be no further away than 2/sin(26) = 4.56 times
the radius of the larger star.


The velocity curve of the star
http://homepage.mac.com/antallan/images/algol/hilla.jpg
shows max and min velocities at phases 0.06 and 0.7, or 144 degrees
apart, not 180 degrees, so it would not be possible to claim a circular
orbit with a c-constant model, meaning that the orbit would have to be
elliptical and periastron considerably closer than 4.56 times the radius
of the larger star, making the system even more unstable.

I think you guys that believe c is constant in all frames of reference
have some explaining to do, observation shows your numbers don't add up,
we've been looking at Algol for well over 1000 years and it hasn't blown
up yet; you have a mystery on your hands.

Fortunately for those of us that think Einstein's first postulate is
exact and his second only a first approximation, in not sharing his view
that the second postulate is exact and the first postulate is only a
first approximation do not share your mystery.
