The propagation of meridional circulation below the base of the convection zone (CZ) of low-mass stars may play a crucial role in the transport of angular momentum and also significantly contribute to the transport of chemical species and magnetic fi

Ultra-massive white dwarfs (⁠1.05M⊙≲MWD⁠) are particularly interesting objects that allow us to study extreme astrophysical phenomena such as type Ia supernovae explosions and merger events. Traditionally, ultra-massive white dwarfs are thoug

Convective dynamics with mixed temperature boundary conditions: why thermal relaxation matters and how to accelerate it

Autor: Lydia Korre, Evan H. Anders, Geoffrey M. Vasil, Benjamin P. Brown

Astrophysical simulations of convection frequently impose different thermal boundary conditions at the top and the bottom of the domain in an effort to more accurately model natural systems. In this work, we study Rayleigh-Benard convection (RBC) und

This doctoral work is motivated by the Sun and solar-type stars, which consist of an unstable convection zone (CZ) that lies on top of a stably stratified radiative zone (RZ). The dynamics occurring at the CZ-RZ interface are not well understood, and
