Nuclear Equation of State for Hot Dense Matter

Nuclear equation of state (EOS) is constructed with energy density functional (EDF) and liquid drop model (LDM) technique. Compared with the classical LDM approach containing alpha particle, deutron, triton, and helio are added to construct nuclear EOS. Energy density functional parameters are constrained by theoretical neutron matter calculation, symmetric nuclear matter properties, and maximum mass of neutron stars. The nuclear surface tension and the critical temperature necessary for the free energy of finite nuclei are calculated in a consistent way. In this talk, I will present and discuss the current results obtained from LDM and EDF with most recent parameters.

Simulations of Core-Collapse Supernovae: Understanding the birth properties of compact objects and beyond

Core-collapse supernovae, the explosions of massive stars, have remained one of the outstanding challenges in computational astrophysics for decades, and the mechanism by which they explode has long eluded us. However, there is now a growing number of 3D simulations that develop successful explosions driven by neutrino heating in conjunction with violent aspherical fluid motions. One of the main challenges is now to corroborate the simulations by confronting them with observables. Among these observables, the birth properties of compact remnant are within close reach. Recent 3D models already obtain neutron star masses, kicks, birth spin periods within the observed range, and predict interesting and possible testable correlations between these neutron star properties. Furthermore, 3D simulations of partially successful fallback supernovae suggest a pathway for the formation of black holes with substantial kicks, for which there is increasing observational evidence. I will conclude with an outlook on other observables that may help to further unravel the inner workings of the multi-dimensional neutrino-driven engine.
