Penetrative convection in stars
Abstract
Methods developed to describe stellar convection are reviewed, and their suitability for describing the penetration of convective motions into stable surroundings is considered. Phenomenological approaches based on local and nonlocal mixing-length treatments are examined along with procedures based on the concept of thermals and direct approaches for treating Boussinesq convection as well as convection in a stratified medium. Possible observational tests of the various methods are outlined.
