The Tale of a Hungry Subgiant and Its Brown Dwarf: Interior Radiative Damping Dominates the Tidal Evolution of TOI-5882
Ritvik Sai Narayan, Melinda Soares-Furtado, Richard H. D. Townsend
We present a self-consistent tidal evolution framework that couples binary evolution from MESA to the full linear tidal response from GYRE-tides. Applying this framework to TOI-588…

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…

The evolutionary and asteroseismic imprints of mass accretion. The 10 M Cep case study
A. Miszuda, Z. Guo, R. H. D. Townsend
We investigate the structural and asteroseismic consequences of mass accretion in massive stars within close binary systems. Using MESA, we model the evolution of the 10 M$_{\odot}…
