mesa-users] Regarding the MESA EOS

[Aaron Dotter]

Hi Ricky,

Actually, the eos module works with Pgas, see mesa/eos/public/eos_def.f for
a list of variables that it works with.

So, for example, the eos call that returns P(Rho,T) = eosDT_get actually
returns Pgas.  See also mesa/eos/public/eos_lib.f for a list of different
eos subroutines.  A function called Radiation_Pressure(T) is included in
eos_lib as a convenience.

Best wishes,
Aaron
