Multidimensional Radiation Hydrodynamics Simulations of Supernova 1987a Shock Breakout

Abstract

• The phenomenon of shock breakout is the first electromagnetic signal from CCSN as the shockwave propagates to the stellar surface and the opacity allows radiation to escape. Shock breakout holds vital informations from progenitor star and environments, particularly its final stage of stellar evolution. • To address between 1D rad-hydro simulation and 2D gray simulation, we use CASTRO code MGFLD to simulate 2D cylindrical shock breakout using SN1987a progenitor model from Love-grove et al. 2017, our investigation primarily focus on the structures evolution and angle-dependent luminosity variation curve. • Moreover, our methods extend to complex scenarios including CSM structures and perturbation modes. Additionally, we conduct some RSG, Binary, and 3D simulations. • During this lunch talk, I shall present an introduction to basic ideas of shock breakout, then explain our methodology using CASTRO and share some simulations results, showcasing the evolution of structures and luminosity variation curve.
