Supernova Explosion and Black Hole Formation with QCD phase transition

Abstract:
Hadronic matter undergoes a deconfinement transition to quark matter at high temperature and/or high density. It would be realized in not only compact stars but also collapsing cores of massive stars. The fates of core collapses are investigated for various cases. Equations of state including the QCD phase transition with different values of bag constant are used. As a result, for the case with a small bag constant (i.e. the transition occurs at low density), the second bounce revives the shock wave leading to explosion for the model with 15 solar mass. The systematics on the bag constant is also studied for the black hole formation of a 40 solar mass progenitor.
