Abstract

We briefly present our recent progress to model in 3-D the excitation and propagation of internal waves in the deep solar radiative interior. By modeling a rotating spherical convection zone on top of a radiative interior with a realistic seismically calibrated stable stratification (i.e solar-like Brunt-Väisälä frequency), we are able to generate a large spectrum of internal waves and modes thanks to the continuous pummeling of convective plumes. When comparing with an adiabatic oscillation code we find a good overall agreement and confirm that those waves are gravity waves.
