The propagation of neutrino-driven jets in Wolf-Rayet stars
Hiroki Nagakura
We numerically investigate the jet propagation through a rotating collapsing Wolf-Rayet star with detailed central engine physics constructed based on the neutrino-driven collapsar…
Post-shock-revival evolutions in the neutrino-heating mechanism of core-collapse supernovae
Yu Yamamoto, Shin-ichiro Fujimoto, Hiroki Nagakura +1
We perform some experimental simulations in spherical symmetry and axisymmetry to understand the post-shock-revival evolution of core-collapse supernovae. Assuming that the stalled…
Semi-dynamical approach to the shock revival in core-collapse supernovae
Hiroki Nagakura, Yu Yamamoto, Shoichi Yamada
We develop a new semi-dynamical method to study shock revival by neutrino heating in core- collapse supernovae. Our new approach is an extension of the previous studies that employ…
Core-Collapse Supernovae as Supercomputing Science: a status report toward 6D simulations with exact Boltzmann neutrino transport in full general relativity
Kei Kotake, Kohsuke Sumiyoshi, Shoichi Yamada +4
This is a status report on our endeavor to reveal the mechanism of core-collapse supernovae (CCSNe) by large-scale numerical simulations. Multi-dimensionality of the supernova engi…
