Abstract: Mode line widths and amplitudes provide valuable information on stellar oscillation excitation and damping, and thus on physical processes such as convection, radiative losses and convection/pulsation coupling. We present preliminary results for mode line widths obtained by fitting mode spectra from Kepler observations. The difficulties of such fitting are discussed as well as these preliminary estimates in the context of models.
