Dive into the heart of red giant stars to better understand our Galaxy

Résumé

The availability of asteroseismic constrains for of large sample of stars observed with CoRoT and Kepler paves the way for statistical studies of the seismic properties of stellar populations, and becomes a powerful tool to better understand stellar structure and evolution. Here I present predictions of stellar models computed with the code STAREVOL including thermohaline mixing together with rotational mixing. I compare the theoretical predictions for the chemical properties of stars with recent spectroscopic of both field and cluster stars observations, and discuss the effects of both mechanisms on asteroseismic diagnostics, as well as on Galactic chemical evolution of helium-3.
