[mesa-users] ionization fraction or kap table ?

[Jing L. <jin...@gm...>]

Dear mesa users,

1, Are there parameters in mesa that tells the ionization fraction of (HI
to HII) and of (HeI to HeII) please? I search around
mesa/star/public/star_data.inc, but did not find any. But maybe I miss
something there.

2, For calculating kappa mechanism due to H or He opacity bumps for driving
stellar oscillation, which kappa table and eos table should be adopted
please? The default in mesa-r8118 are

kappa_file_prefix = 'gn93'

eos_file_prefix = 'mesa'
eosDT_Z1_suffix = '_CO_1'
eosPT_Z1_suffix = '_CO_1'

Many thanks 😊😊😊😊

Sincerely,
Jing
