| contents | We model the stochastic excitation of acoustic modes in solar-like pulsators taking into account the action of differential rotation. We derive the theoretical formalism for the stochastic excitation with differential rotation and make use of rotating convection Mixing-Length Theory to assess how the convective velocity is modified by rotation. Finally, we use the stellar structure and evolution code MESA combined with the stellar pulsation code GYRE to compute acoustic modes amplitudes. |
