  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.
