Damping rates versus mode frequency, computed for a model of a mass of M = 1.1   M_⊙ and an effective temperature of T_eff = 6026 K on the main sequence. The damping has been computed as described in Sect. 2.2. The solid line corresponds to the total damping rate, while the dash-dotted line corresponds to the contribution of the perturbation of turbulent pressure and the dashed line to the absolute value of the contribution of the entropy perturbations (see Eq. (1)). The vertical dotted line corresponds to ν_max.
