Résumé
Cesam2k20 is a community stellar evolution code publicly available. It is able to compute standard as well as non standard models, including transport of chemical elements and angular momentum, mass loss, planetoide accretion, entropy calibrated convection, radiative acceleration, etc. It is the latest public version of the CESAM (Code d' Évolution Stellaire, Adaptatif et Modulaire) stellar evolution code, originally developed by Pierre Morel. We describe bellow the main numerical and input physics aspects of the code, as well as future plans for its development.
