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…
An Educational Guide for 2D Stellar Structure Calculations of Rapidly Rotating Stars using the ESTER code
Russel White, Jane Pratt, Michel Rieutord
The Evolution STEllaire en Rotation (ESTER) code is the first 2D stellar structure code to be made open-source and freely available to the astronomy and astrophysics community. An…
Convective shells in the interior of Cepheid variable stars: overshooting models based on hydrodynamic simulations
Maxime Stuck, Jane Pratt, Isabelle Baraffe +5
Because Cepheid variable stars have long been used as a cosmic benchmark, the accuracy of stellar evolution models for Cepheids have wide-reaching effects. Our goal is to provide a…
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…
The shape of convection in 2D and 3D global simulations of stellar interiors
M. -G. Dethero, J. Pratt, D. G. Vlaykov +5
Theoretical descriptions of convective overshooting often rely on a one-dimensional parameterization of the flow called the filling factor for convection. Several definitions of th…
Effects of stratification on overshooting and waves atop the convective core of main-sequence stars
Adrien Morison, Arthur Le Saux, Isabelle Baraffe +5
As a massive star evolves along the main sequence, its core contracts, leaving behind a stable stratification in helium. We simulate 2D convection in the core at three different st…
