Effects of mixing processes on spectroscopic and asteroseismic quantities inside red giant stars - Consequences on the Galactic evolution of light elements

mardi 2 avril 2013, 14h

salle de conférences de l’observatoire

Nadège LAGARDE, Université de Birmingham

Résumé :

The availability of asteroseismic constrains for a large sample of stars from CoRoT and Kepler paves the way for various statistical studies of the seismic properties of stellar populations, and becomes a powerful tool to
better understand stellar structure and evolution. I will present predictions of stellar models computed with the code STAREVOL including thermohaline mixing together with rotational mixing. I will compare our theoretical predictions with recent spectroscopic observations, and discuss the effects of both mechanisms on asteroseismic diagnostics, as well as on galactic evolution of light elements.
