Abstract:
Multi-dimensional hydrodynamical simulations provide a powerful approach to describe complex processes in stars such as convection, convective penetration and waves. These processes strongly impact the internal structure and evolution of stars, contributing to mixing and transport of angular momentum. I will present the challenges and potential of hydrodynamical simulations devoted to stellar interiors. I will also show how the study of internal waves excited by convection could unveil the secrets of the deepest and most invisible stellar regions.
Bio:
Isabelle Baraffe is a distinguished Chair Professor of Astrophysics at the University of Exeter, where she has been a faculty member since 2010. Prior to joining Exeter, Professor Baraffe held several prominent academic positions. She was a Professor of Astrophysics at the Centre de Recherche Astrophysique de Lyon (CRAL) in France and served as an Associate Professor in the Physics Department at the Ecole Normale Supérieure in Lyon. Her early career included postdoctoral research at the University of Göttingen’s Sternwarte in Germany and at the Max-Planck Institut für Astrophysik in Garching, Germany. She has made significant contributions in stellar and planetary physics and evolution, stellar hydrodynamics, exoplanets, and planetary atmospheric dynamics. Her contributions to these fields have been widely recognised, earning her several prestigious awards., including the Medal of the Universe from the French Academy of Science in 2025, the Fred Hoyle Medal and Prize from the IoP in 2024, the Lodewijk Woltjer Lecture from the European Astronomical Society in 2023, the Viktor Ambartsumian International Science Prize in 2020.
