A New Approach to Mass and Radius of Neutron Stars with Supernova Neutrinos
Ken'ichiro Nakazato, Hideyuki Suzuki
Neutron stars are formed in core-collapse supernova explosions, where a large number of neutrinos are emitted. In this paper, supernova neutrino light curves are computed for the c…
Influence of density dependence of symmetry energy in hot and dense matter for supernova simulations
Kohsuke Sumiyoshi, Ken'ichiro Nakazato, Hideyuki Suzuki +2
We study the influence of density-dependent symmetry energy at high densities in simulations of core-collapse supernovae, black hole formation and proto-neutron star cooling by ext…
Cooling timescale for protoneutron stars and properties of nuclear matter: Effective mass and symmetry energy at high densities
Ken'ichiro Nakazato, Hideyuki Suzuki
The cooling process of a protoneutron star is investigated with focus on its sensitivity to properties of hot and dense matter. An equation of state, which includes the nucleon eff…
Spectrum of the Supernova Relic Neutrino Background and Metallicity Evolution of Galaxies
Ken'ichiro Nakazato, Eri Mochida, Yuu Niino +1
The spectrum of the supernova relic neutrino (SRN) background from past stellar collapses including black hole formation (failed supernovae) is calculated. The redshift dependence…
Supernova Neutrino Light Curves and Spectra for Various Progenitor Stars: From Core Collapse to Proto-neutron Star Cooling
Ken'ichiro Nakazato, Kohsuke Sumiyoshi, Hideyuki Suzuki +3
We present a new series of supernova neutrino light curves and spectra calculated by numerical simulations for a variety of progenitor stellar masses (13-50Msolar) and metallicitie…
