Cesam2k20: A code for a new generation of stellar evolution models. I. Description of the code
L. Manchon, M. Deal, J. P. C. Marques +1
We present Cesam2k20, the latest version of the hydrostatic stellar evolution code CESAM originally developed by P. Morel and collaborators. Over the last three decades, it has und…

Entropy-calibrated stellar modeling: Testing and improving the use of prescriptions for entropy of adiabatic convection
L. Manchon, M. Deal, M. -J. Goupil +7
The modeling of convection is a long standing problem in stellar physics. Up-to-now, all ad hoc models rely on a free parameter alpha (among others) which has no real physical just…

Influence of metallicity on the near-surface effect on oscillation frequencies
L. Manchon, K. Belkacem, R. Samadi +4
The CoRoT and Kepler missions have provided high-quality measurements of the frequency spectra of solar-like pulsators, enabling us to probe stellar interiors with a very high degr…
