Thermohaline Mixing: Does It Really Govern the Atmospheric Chemical Composition of Low-Mass Red Giants?
stars abundances — stars evolution — stars interiors
2010/11/12
First results of our 3D numerical simulations of thermohaline convection driven by 3He burning in a low-mass RGB star at the bump luminosity are presented. They confirm our previous conclusion that th...

Context. Mass loss of ∼ 0.1-0.3 M⊙ from Population II red giant stars (RGB) is a requirement of stellar evolution theory in order to account for several observational evidences in globular clust...
