Solar-like oscillation amplitudes and line-widths as a probe for turbulent convection in stars
R. Samadi, K. Belkacem, M. -J. Goupil +2
Excitation of solar-like oscillations is attributed to turbulent convection and takes place at the upper-most part of the outer convective zones. Amplitudes of these oscillations d…
A closure model with plumes II. Application to the stochastic excitation of stellar p modes
K. Belkacem, R. Samadi, M. -J. Goupil +2
Our goal is to improve the theoretical modelling of stochastic excitation of p modes by turbulent convection. With the help of the closure model with plume (CMP) developed in a com…
A closure model with plumes I. The solar convection
K. Belkacem, R. Samadi, M. -J. Goupil +1
Oscillations of stellar p modes, excited by turbulent convection, are investigated. We take into account the asymmetry of the up and downflows created by turbulent plumes through a…
