Stochastic excitation of nonradial modes II. Are solar asymptotic gravity modes detectable?
K. Belkacem, R. Samadi, M. J. Goupil +3
Detection of solar gravity modes remains a major challenge to our understanding of the innerparts of the Sun. Their frequencies would enable the derivation of constraints on the co…
Modelling the excitation of acoustic modes in Alpha Cen A
R. Samadi, K. Belkacem, M. J. Goupil +2
We infer from different seismic observations the energy supplied per unit of time by turbulent convection to the acoustic modes of Alpha Cen A (HD 128620), a star which is similar…
Stochastic excitation of non-radial modes I. High-angular-degree p modes
K. Belkacem, R. Samadi, M. J. Goupil +1
Turbulent motions in stellar convection zones generate acoustic energy, part of which is then supplied to normal modes of the star. Their amplitudes result from a balance between t…
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…
