SUMMARY

The discussion centers on determining the mass of red giants and AGB stars using their luminosities, radii, and core masses. A specific reference is made to the paper "Change et al. Astrophys.J. 732 (2011) 25," which provides radius-density profiles essential for this calculation. The key takeaway is that knowing the core mass allows for the derivation of the mass-luminosity relationship through a straightforward integral. This method is crucial for astrophysicists studying stellar evolution.

PREREQUISITES
  • Understanding of stellar evolution concepts
  • Familiarity with mass-luminosity relationships in astrophysics
  • Knowledge of integral calculus for deriving relationships
  • Access to astrophysical literature, particularly on red giants and AGB stars
NEXT STEPS
  • Research the mass-luminosity relationship specific to red giants and AGB stars
  • Study the integral methods used in stellar mass calculations
  • Review the findings in "Change et al. Astrophys.J. 732 (2011) 25" for detailed equations
  • Explore additional resources on radius-density profiles in stellar astrophysics
USEFUL FOR

Astronomers, astrophysicists, and students studying stellar evolution and mass-luminosity relationships will benefit from this discussion.

TL;DR
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.
