Stellar granulation.
Abstract
The spectroscopic features that can be interpreted as signatures of stellar granulation are described. Special attention is given to theoretical models of stellar granulation and synthetic photospheric line profiles in solar-type stars. Problems involved in observing subtle photospheric line asymmetries caused by stellar granulation are illustrated, and indirect methods that can be used for imaging stellar surfaces are discussed.
