Default Why are the 'Fixed Stars' so FIXED?

Tidal effects from the closely orbiting pulsar


Bad choice of words. Sorry. I see there has been some
confusion in this thread about who was orbiting whom. The
pulsar weighs 1.438 +/- 0.024 solar masses, and its companion
weighs 0.2038 +/- 0.022 solar masses, so if anything, one
should say that the white dwarf orbits the pulsar.

Actually, of course, they orbit around their common
barycenter, so what's the big deal?


It is very BIG.

It means I don't need anywhere near as much extinction to explain the distance
anomaly. Orbit pitch can also be included in the equation.

would be expected to drive complex "weather" patterns on
its surface. However, any luminosity variances due to
these effects would be completely negligible relative to
the flux of black body radiation.
