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.
