What red giant seismology is teaching us about stellar physics
Sébastien Deheuvels (IRAP (Toulouse, France))
Since the detection of non-radial oscillations in over 10,000 red giants by space missions CoRoT and Kepler, the seismology of these objects has rightfully gained interest among the stellar physics community. The detection of mixed gravity-pressure modes has indeed made it possible to peer into the cores of red giants. This is currently bringing stringent constraints on several physical processes in stellar interiors that remain poorly understood but play a central role in stellar evolution, such as the nature and efficiency of mixing beyond boundaries of convective regions, or the way angular momentum is transported inside stars. We here give an overview of what the seismology of red giants has already taught us about such processes, and highlight the potential of dipole mixed modes in red giants for new advances in stellar physics.
