Phenomenological turbulent effects of core-collapse supernovae
Speaker: Shunsuke Sasaki
Abstract:
It is not yet known how massive the star can explode as core collapse supernova (CCSN), how much explosive energy, neutrinos and other quantities will be observed when it explodes. Researches into simulations of CCSN mechanism have succeeded in showing that such explosions are possible even in three-dimensional (3D) simulations. It was also revealed that turbulence associated with neutrino heating plays an important role in the explosion. This has led to an active discussion on the relationship between the quantity of progenitor before the explosion and the physical quantity of CCSNe, which is called progenitor dependence. In recent years, the development of phenomenological one-dimensional simulations (1D+) introducing turbulence effects has become an urgent issue in order to investigate the progenitor dependence more realistically. We developed 1D+ and we got the result that our 1D+ can mimic the shock evolution in 3D. In this tolk, I will explain our 1D+ and preliminary results about progenitor dependence.
