Numerical 3D constraints on convective eddy time-correlations : consequences for stochastic excitation of solar p modes
R. Samadi, A. Nordlund, R. F. Stein +2
A 3D simulation of the upper part of the solar convective zone is used to obtain information on the frequency component, chi_k, of the correlation product of the turbulent velocity…

Numerical constraints on the model of stochastic excitation of solar-type oscillations
R. Samadi, A. Nordlund, R. F. Stein +2
Analyses of a 3D simulation of the upper layers of a solar convective envelope provide constraints on the physical quantities which enter the theoretical formulation of a stochasti…

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…
