Extra–Mixing Processes in Asymptotic Giant Branch Stars

Abstract

Extra mixing is the mixing of material in regions that are stable against convection. We identify two situations in asymptotic giant branch stars where extra mixing is thought to be required. We then discuss four physical processes that might be the cause of such mixing: convective overshooting, rotational mixing, internal gravity waves and thermohaline mixing. The first three are discussed in terms of the formation of the 13C pocket, while the last is discussed in relation to abundance changes during the interpulse. We round off this review with some comments on how progress might be made in this area.
