Type IIb Supernova Progenitors in 3D: Variability and Episodic Mass Loss revealed by Radiation-Hydrodynamics Simulations

Jared A. Goldberg, Yan-Fei Jiang, Lars Bildsten +1

We present the first 3D Radiation-Hydrodynamics simulations of partially-stripped ($M_{\mathrm{core}}\sim 10M_{\odot }$, $M_{\mathrm{env}}\sim 0.1-1M_{\odot }$) Yellow Supergiant ($L\sim 10^5$,…
