Influence of effective mass of the relativistic mean field theory on core collapse supernovae and compact objects
Kohsuke Sumiyoshi, Hajime Togashi, Shun Furusawa +4
We study the influence of the effective mass in the relativistic mean field (RMF) theory on the properties of the central core of collapse-driven supernovae and the formation of co…
Role of symmetry energy at subnuclear densities in protoneutron star crusts
Ken'ichiro Nakazato, Hajime Togashi, Kohsuke Sumiyoshi +1
The impact of matter properties at subnuclear densities on the evolution of protoneutron stars is investigated. Several models of nuclear equation of state (EOS) are constructed wi…
Study of the neutrino-oxygen cross sections of the charged-current reaction 16O()16N(0 MeV,) and the neutral-current reaction 16O(')16O(12.97/12.53 MeV,), producing high-energy gamma rays
Makoto Sakuda, Toshio Suzuki, Ken'ichiro Nakazato +1
In the previous work, we discussed the cross section and the detection of 4.4-MeV rays produced in the neutrino neutral-current (NC) reaction O()O(…
Nuclear equation of state for core-collapse supernova simulations with realistic nuclear forces
H. Togashi, K. Nakazato, Y. Takehara +3
A new table of the nuclear equation of state (EOS) based on realistic nuclear potentials is constructed for core-collapse supernova numerical simulations. Adopting the EOS of unifo…
Global Simulations of Magnetorotational Instability in The Collapsed Core of A Massive Star
Hidetomo Sawai, Shoichi Yamada, Hideyuki Suzuki
We performed the first numerical simulations of magnetorotational instability from a sub-magnetar-class seed magnetic field in core collapse supernovae. As a result of axisymmetric…
Effects of Resistivity on Magnetized Core-Collapse Supernovae
Hidetomo Sawai, Shoichi Yamada, Kei Kotake +1
We studied roles of a turbulent resistivity in the core-collapse of a strongly magnetized massive star, carrying out 2D-resistive-MHD simulations. The three cases with different in…
