Simulation of rings surrounding the progenitor of SN1987A
Jireš, Michal ; Pejcha, Ondřej (advisor) ; Calderón Espinoza, Diego Nicolas (referee)
SN1987A, the first supernova visible by the naked eye since 1600s, is anomalous by existence of preexisting triple ring nebula around it. One candidate explanation of the nebula is a binary merger of SN1987A's progenitors. This was already modelled in previous work with smoothed-particle hydrodynamics code GADGET. This thesis aims to replicate this model using mesh-based hydrodynamics code Athena++ and compare it. We focus on ejected mass per latitude distribution and total ejected mass. 1
