Is there any theoretical explanations for HR diagram or Mass-Luminosity relation?

Hi!

Is there any theoretical explanations for HR diagram or Mass-
Lumionsity relation?
Or Mass-Radius relation?


Thanks in advance

Stefan - Boltzman law of radiation plus temperature sensitivity of
various nuclear reactions. Throw in modified gas laws to get the core
temperature and pressure. There are text books that go into detail. A
few years ago, the big doubt about it was the so called missing
neutrino problem but that has now been resolved.

To get the mass-luminosity relation, you don't need any information about the
nuclear reactions. These are only required if you need to work out the radius also.
