Transition Layers of F and Early G Giants
Abstract
Giants are especially well suited to study the dependence of transition layer stratifications on v sini and log Teff because they are a group of stars of nearly the same mass, age and chemical composition. We want to observe additional F and early G giants in order to better understand which heating mechanism(s) are responsible for the heating of the transition layers. We also want to determine N/C and Si/C abundance ratios which appear to be abnormal for several F giants in contradiction to theoretical expectations.
