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…

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…

RUBIS: a simple tool for calculating the centrifugal deformation of stars and planets
Pierre S. Houdayer, Daniel R. Reese
We present RUBIS (Rotation code Using Barotropy conservation over Isopotential Surfaces), a fully Python-based centrifugal deformation program available at \url{https://github.com/…
