Mass-luminosity relationship for red giants and AGB stars?

In summary, the mass-luminosity relationship for red giants and AGB stars describes the correlation between a star's mass and its luminosity. It states that the more massive a star is, the more luminous it will be due to its ability to sustain more nuclear fusion reactions. This relationship differs from that of main sequence stars, as red giants and AGB stars have evolved past the main sequence stage. However, it is not consistent for all stars of this type, as other factors can affect a star's luminosity. The relationship was discovered through observations and theoretical models and can be used to estimate the mass of a red giant or AGB star, but it is not as accurate as other methods.

TL;DR Summary
Hello! I'm attempting to find the mass of a red giant and an AGB star.
Hello! I'm attempting to find the mass of a red giant and an AGB star. I have their luminosities, radii, and the masses of their cores. I'm looking for some kind of mass-luminosity relationship. Do you know of any, or do you know of a good place to look for such equations? Thanks!

Change et al. Astrophys.J. 732 (2011) 25 has radius-density profiles. If you know the core mass, you're just one integral away from all you need.
