Phase-space averaging for stellar convection I. Liouvillian dynamics
P. S. Houdayer, M. Rieutord
Convection remains one of the main uncertain links between multidimensional hydrodynamics and one-dimensional stellar evolution. In particular, transition regions such as near-surf…
White paper on the relevance of the European Solar Telescope (EST) for the French heliophysics
E. Pariat, Q. Noraz, B. Perri +61
The project of the European Solar Telescope aims to provide a state-of-the art infrastructure to study the Sun and its interactions with Earth and the heliosphere. This 4.2m apertu…
Phase-space averaging for stellar convection II. Maximum-entropy closures for mixed radiative-convective envelopes
P. S. Houdayer, M. Rieutord
Surface convection in cool stars sets the entropy jump between the atmosphere and the deep convective envelope, and therefore affects the radius and structure of one-dimensional st…
Angular momentum relaxation in models of rotating early-type stars
Michel Rieutord, Enzo Enzo Brossier-Sécher, Joey Mombarg
The rotational evolution of stars is still an open question of stellar physics because of the numerous phenomena that can contribute to the distribution of angular momentum. This p…
