- Abstract
Mode line widths and amplitudes provide valuable information on stellar oscillation excitation and damping, and thus on physical processes suchas convection, radiative losses and convection/pulsation coupling. Wepresent preliminary results for mode line widths obtained by fittingmode spectra from Kepler observations. The difficulties of such fittingare discussed as well as these preliminary estimates in the context ofmodels.
