Red giant branch stars: the theoretical framework. (Review).
SALARIS M., CASSISI S. and WEISS A.
Abstract (from CDS):
We review the current status of red giant star modeling, discussing in detail the still-existing uncertainties affecting the model input physics (e.g., electron conduction opacity, treatment of the superadiabatic convection) and the adequacy of the physical assumptions built into the model computations.
We compare theory with several observational features of the red giant branch in Galactic globular clusters, such as the luminosity function ``bump'', the luminosity of the red giant branch tip, and the envelope chemical abundance patterns, to show the level of agreement between current stellar models and empirical data concerning the stellar luminosities, star counts, and surface chemical abundances.
