Explodability of Core-Collapse Supernovae with a Transition to Quark Matter

The effects of a phase transition to quark mater during core-collapse supernovae has been a subject of considerable interest. In the work reported here we extend this study to an exploration of the role of a transition to quark matter on the explodability of supernovae driven by neutrino heated convection in the context of relativistic supernova turbulence in reduced dimensionality (STIR) [1]. We use the DD2F-SF hybrid quark-hadronic equation of state (EOS) with a first-order phase transition and GR1D, a one-dimensional general relativistic hydrodynamics code. We study solar metallicity progenitors with zero-age main sequence masses in the range 15 - 25 M_☉. We examine the emergent neutrino spectra and evolution of the shock front and thermodynamic variables with and without a transition to quark matter and with or without the onset of STIR. Effects on the explodability of progenitors will be discussed.
