On the feasibility of inverting the rotation of the solar core with mixed f/g modes
Armand Leclerc, Arthur Le Saux, J. M. Joel Ong +1
Context: Thanks to helioseismology, the rotation profile of the Sun has been measured with great precision down to 20% of its total radius. This rotation profile is used as a calib…
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…
A core-sensitive mixed / mode of the Sun predicted by wave topology and hydrodynamical simulation
Arthur Le Saux, Armand Leclerc, Guillaume Laibe +2
Helioseismology has revolutionized our understanding of the Sun by analyzing its global oscillation modes. However, the solar core remains elusive, limiting a full understanding of…
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…
