Toward Radiation-Magnetohydrodynamic Simulations in Core-Collapse Supernovae
Kei Kotake, Naofumi Ohnishi, Shoichi Yamada +1
We report a current status of our radiation-magnetohydrodynamic code for the study of core-collapse supernovae. In this contribution, we discuss the accuracy of our newly developed…
Gravitational Collapse and Neutrino Emission of Population III Massive Stars
Ken'ichiro Nakazato, Kohsuke Sumiyoshi, Shoichi Yamada
Pop III stars are the first stars in the universe. They do not contain metals and their formation and evolution may be different from that of stars of later generations. In fact, a…
Effects of Magnetic Fields on Proto-Neutron Star Winds
Hirotaka Ito, Shoichi Yamada, Kohsuke Sumiyoshi +1
We discuss effects of magnetic fields on proto-neutron star winds by performing numerical simulation. We assume that the atmosphere of proto-neutron star has a homogenous magnetic…
Numerical Analysis on Standing Accretion Shock Instability with Neutrino Heating in the Supernova Cores
Naofumi Ohnishi, Kei Kotake, Shoichi Yamada
We have numerically studied the instability of the spherically symmetric standing accretion shock wave against non-spherical perturbations. We have in mind the application to the c…
Postbounce evolution of core-collapse supernovae: Long-term effects of equation of state
K. Sumiyoshi, S. Yamada, H. Suzuki +3
We study the evolution of supernova core from the beginning of gravitational collapse of a 15Msolar star up to 1 second after core bounce. We present results of spherically symmetr…
An approach toward the successful supernova explosion by physics of unstable nuclei
K. Sumiyoshi, S. Yamada, H. Suzuki +2
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 gen…
