comment Resolving power of ultra-telescopes
@RobJeffries: the idea of an interferometric array is the idea behind Antoine Labeyrie's "hypertelescope", which occasionally gets coverage.

comment Does degeneracy affect the adiabatic relation?
No time to answer properly now, but I'm with @KyleKanos that it's a coincidence. For the white dwarf, $K$ can be computed for a given mean molecular weight. So it's the same in all white dwarfs. In the ideal gas relation, however, I think $K$ is set by the entropy/temperature of the gas, and can thus vary. I stand to be corrected, though.
