One-dimensional (1D) stellar evolution models are widely used across various astrophysical fields, however they are still dominated by important uncertainties that deeply affect their predictive power. Among those, the merging of independent convecti... Read More about Shell mergers in the late stages of massive star evolution: new insight from 3D hydrodynamic simulations.

3D Simulations of Magnetoconvection in a Rapidly Rotating Supernova Progenitor (2023)
Journal Article

We present a first 3D magnetohydrodynamic (MHD) simulation of oxygen, neon and carbon shell burning in a rapidly rotating 16M⊙ core-collapse supernova progenitor. We also run a purely hydrodynamic simulation for comparison. After $\mathord \approx 18... Read More about 3D Simulations of Magnetoconvection in a Rapidly Rotating Supernova Progenitor.

We investigate the impact of strong initial magnetic fields in core-collapse supernovae of non-rotating progenitors by simulating the collapse and explosion of a 16.9 M-circle dot star for a strong- and weak-field case assuming a twisted-torus field...
