Consequences of the non gaussian character of the stochastic excitation for solar-type oscillations
R. Samadi, A. Nordlund, R. F. Stein +2
Our recent study, based on a 3D numerical simulation, suggested that the stochastic excitation of solar p-modes has a non gaussian nature and a non gaussian model was proposed whic…

Oscillation power across the HR diagram : sensitivity to the convection treatment
Reza Samadi, Guenter Houdek, Marie-Jo Goupil +2
Solar-like oscillations are stochastically excited by turbulent convection. In this work we investigate changes in the acoustic oscillation power spectrum of solar-type stars by va…

Stochastic excitation of stellar oscillations
Reza Samadi
Excitation of solar oscillations is attribued to turbulent motions in the solar convective zone. It is also currently believed that oscillations of low massive stars (M <2 Mo) - wh…
