Theoretical asteroseismology of solar-like oscillations

Abstract

Having a rich acoustic oscillation spectrum makes solar-like stars particularly interesting for studying fluid-dynamical aspects of the stellar interior. I present some of the recent progress in formulating the physical processes that drive the acoustic oscillations to the observed amplitudes via their coupling with the turbulent velocity field in the outer convectively unstable stellar layers. I shall also discuss some asteroseismic diagnostic techniques that allow us to measure some of the gross stellar properties derived from a seismic signature contained in the variation of the large frequency separation of measured low-degree acoustic modes.
