Effect of local treatments of convection upon the solar p-mode excitation rates
R. Samadi, M. -J. Goupil, Y. Lebreton +2
We compute, for several solar models, the rates P at which the solar radial p modes are expected to be excited. The solar models are computed with two different local treatments of…
Seismic diagnostics on stellar convection treatment from oscillation amplitudes of p-modes
R. Samadi, M. J. Goupil, Y. Lebreton +2
The excitation rate P of solar p-modes is computed with a model of stochatic excitation which involves constraints on the averaged properties of the solar turbulence. These constra…
A study of convection with delta Scuti stars in open clusters: Pleiades
J. C. Suarez, E. Michel, G. Houdek +2
In this work we propose a preliminary seismic investigation of Scuti stars in the Pleiades cluster, focusing on potential diagnostics of convection and core-overshooting. Takin…
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…
Oscillation power as a test of stellar turbulence : Scanning the HR diagram
Reza Samadi, Marie-Jo Goupil, Yveline Lebreton +1
The acoustic power injected by turbulent convection into solar-like oscillations depends on the details of the turbulent spectrum. A theoretical formulation for the oscillation pow…
