Effect of the radiative background flux in convection
A. Brandenburg, K. L. Chan, A. Nordlund +1
Numerical simulations of turbulent stratified convection are used to study models with approximately the same convective flux, but different radiative fluxes. As the radiative flux…
Oscillation power spectra of the Sun and of Alpha Cen A: observations versus models
R. Samadi, M. J. Goupil, F. Baudin +4
Hydrodynamical, 3D simulations of the outer layers of the Sun and Alpha Cen A are used to obtain constraints on the properties of turbulent convection in such stars. These constrai…
Stochastic excitation of gravity waves by overshooting convection in solar-type stars
Boris Dintrans, Axel Brandenburg, Ake Nordlund +1
The excitation of gravity waves by penetrative convective plumes is investigated using 2D direct simulations of compressible convection. The oscillation field is measured by a new…
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…
Solar Surface Magneto-Convection
Robert F. Stein, Aake Nordlund
Magneto-convection simulations on meso-granule and granule scales near the solar surface are used to study small scale dynamo activity, the emergence and disappearance of magnetic…
Characterizing the dynamic properties of the solar turbulence with 3-D simulations: Consequences in terms of p-mode excitation
R. Samadi, A. Nordlund, R. F. Stein +2
A 3D simulation of the upper part of the solar convective zone is used to derive constraints about the averaged and dynamic properties of solar turbulent convection. Theses constra…
