Neutrino deuteron reaction in the heating mechanism of core-collapse supernovae
S. X. Nakamura, K. Sumiyoshi, T. Sato
We examine a potential role of the neutrino deuteron reactions in the mechanism of supernova explosion by evaluating the energy transfer cross section for the neutrino heating. We…
Dynamics and neutrino signal of black hole formation in non-rotating failed supernovae. II. progenitor dependence
K. Sumiyoshi, S. Yamada, H. Suzuki
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 prec…
Astrophysical Implications of Equation of State for Hadron-Quark Mixed Phase: Compact Stars and Stellar Collapses
Ken'ichiro Nakazato, Kohsuke Sumiyoshi, Shoichi Yamada
We construct an equation of state including the hadron-quark phase transition. The mixed phase is obtained by the Gibbs conditions for finite temperature. We adopt the equation of…
Tables of Hyperonic Matter Equation of State for Core-Collapse Supernovae
C. Ishizuka, A. Ohnishi, K. Tsubakihara +2
We present sets of equation of state (EOS) of nuclear matter including hyperons using an SU_f(3) extended relativistic mean field (RMF) model with a wide coverage of density, tempe…
Appearance of Light Clusters in Post-bounce Evolution of Core-Collapse Supernovae
Kohsuke Sumiyoshi, Gerd Roepke
We explore the abundance of light clusters in core-collapse supernovae at post-bounce stage in a quantum statistical approach. Adopting the profile of a supernova core from detaile…
Alfven Wave-Driven Supernova Explosion
T. K. Suzuki, K. Sumiyoshi, S. Yamada
We investigate the role of Alfven waves in the core-collapse supernova (SN) explosion. We assume that Alfven waves are generated by convections inside a proto-neutron star (PNS) an…
