2010/11/11
Stellar structure and evolution can be studied in great detail by asteroseismic methods, provided data of high precision are available. We determine the effective temperature (Teff), surface gravity (...
Mode width fitting with a simple bayesian approach. Application to CoRoT targets HD 181420 and HD 49933
