Strength of core-envelope coupling in stars (again)
I asked this on the physics SE but it received little attention:
Consider a high-mass zero-age main-sequence (ZAMS) (e.g., $m_{\rm ZAMS} \gtrsim 30\,$M$_{\odot}$) star.
I understand that the core-...

The mass of Subdwarf B progenitors in the main sequence
Note: By "progenitor", I mean "the star as it was when it was still main sequence". Please correct me if I've got the terminology wrong.
Most B-type subdwarfs have mass roughly half that of the Sun. ...

Are there simplified M-L, M-R, and lifetime equations for non main sequence stars?
To give some context - I am trying to create a simple program that outputs the stellar properties of a star when given its initial mass and current age.
e.g.
Input
Initial Mass = 2e30kg
Age = 4.6 ...
