Numerical study of stellar core collapse and neutrino emission using the nuclear equation of state obtained by the variational method

Abstract Core-collapse simulations of massive stars are performed using the equation state (EOS) based on microscopic variational calculation with realistic nuclear forces. Progenitor models initial masses 15, 9.6, and 30 $M$? adopted as examples an ordinary core-collapse supernova a shock stall, low-mass successful explosion, black hole formation, respectively. Moreover, neutrinos emitted from stellar collapse assessed. The EOS is confirmed to work well in all cases. dependencies dynamics, thermal structure, neutrino emission also investigated.
