    Abstract

    In this study we investigate numerically the stellar core collapse and black hole formation taking into account the EOS's involving quarks and/or pions. In our simulations, we utilize the code which solves the general relativistic hydrodynamics and neutrino transfer equations simultaneously, treating neutrino reactions in detail under spherical symmetry. Our results show that quarks and pions shorten the duration of neutrino emission if the collapse is bounced before the black hole formation. In addition, pions make the luminosity and average energy of neutrinos higher before the black hole formation.
