Revealing mixed modes in compressible hydrodynamical simulations of red giant stars
Nils B. de Vries, Arthur Le Saux, Isabelle Baraffe +4
Mixed modes are observed in many low-mass evolved stars. They provide information about core rotation rates of these stars, which are lower than predicted by stellar evolution mode…

Unveiling stellar (and planetary) internal dynamics with the fully compressible MUSIC code
Arthur Le Saux, Isabelle Baraffe, Thomas Guillet +8
Multidimensional hydrodynamical simulations have transformed the study of stellar interiors over the past few decades. Most codes developed during that time use the anelastic appro…

Mixing by Internal Gravity Waves in Stars: Assessing Numerical Simulations Against Theory
Jack Morton, Thomas Guillet, Isabelle Baraffe +5
Here we present a study of radial chemical mixing in non-rotating massive main-sequence stars driven by internal gravity waves (IGWs), based on multi-dimensional hydrodynamical sim…
