We construct the equation of state (EOS) of nuclear matter using the relativistic mean field (RMF) theory in the wide density, temperature range with various proton fractions for the use of supernovaâ€¦ (More)

We construct the equation of state (EOS) of nuclear matter at finite temperature and density with various proton fractions within the relativistic mean field (RMF) theory for the use in the supernovaâ€¦ (More)

We study the black hole formation and the neutrino signal from the gravita-tional collapse of a non-rotating massive star of 40 M âŠ™. Adopting two different sets of realistic equation of state (EOS)â€¦ (More)

We study the influence of the symmetry energy of the equation of state on the thermal evolution of protoneutron stars and the properties of supernova neutrinos by the numerical simulations after theâ€¦ (More)

We study the evolution of supernova core from the beginning of gravitational collapse of a 15M âŠ™ star up to 1 second after core bounce. We present results of spherically symmetric simulations ofâ€¦ (More)

First results of numerical simulations are presented which compute the dynamical evolution of a neutron star with a mass slightly below the minimum stable mass by means of a new implicit (generalâ€¦ (More)

We reanalyze r-process nucleosynthesis in the neutron-rich ejecta from a prompt supernova explosion of a low-mass (11 M ) progenitor. Although it has not yet been established that a prompt explosionâ€¦ (More)

We study the progenitor dependence of the black hole formation and its associated neutrino signals from the gravitational collapse of non-rotating massive stars, following the preceding study on theâ€¦ (More)

We study the explosion mechanism of collapse-driven supernovae by numerical simulations with a new nuclear EOS based on unstable nuclei. We report new results of simulations of general relativisticâ€¦ (More)
