Simulations of Core-collapse Supernovae in Spatial Axisymmetry with Full Boltzmann Neutrino Transport
Hiroki Nagakura,Wakana Iwakami,Wakana Iwakami,Shun Furusawa,Hirotada Okawa,Hirotada Okawa,Akira Harada,Kohsuke Sumiyoshi,Shoichi Yamada,Hideo Matsufuru,Akira Imakura +10 more
TL;DR: In this article, the first results of the spatially axisymmetric core-collapse supernova simulations with full Boltzmann neutrino transport were presented, which amount to a time-dependent five-dimensional (two in space and three in momentum space) problem.
Journal ArticleDOI

Milad Delfan Azari,Shoichi Yamada,Taiki Morinaga,Hiroki Nagakura,Shun Furusawa,Akira Harada,Hirotada Okawa,Hirotada Okawa,Wakana Iwakami,Wakana Iwakami,Kohsuke Sumiyoshi +10 more
TL;DR: In this article, the electron lepton number (ELN) crossing in one of the self-consistent, realistic Boltzmann simulations in two spatial dimensions under axisymmetry was investigated.

Simulations of core-collapse supernovae in spatial axisymmetry with full Boltzmann neutrino transport
Hiroki Nagakura,Wakana Iwakami,Wakana Iwakami,Shun Furusawa,Hirotada Okawa,Hirotada Okawa,Akira Harada,Kohsuke Sumiyoshi,Shoichi Yamada,Hideo Matsufuru,Akira Imakura +10 more
TL;DR: In this article, the first results of spatially axisymmetric core-collapse supernova simulations with full Boltzmann neutrino transport were presented, which amount to a time-dependent 5-dimensional (2 in space and 3 in momentum space) problem in fact.

On the Neutrino Distributions in Phase Space for the Rotating Core-collapse Supernova Simulated with a Boltzmann-neutrino-radiation-hydrodynamics Code
Akira Harada,Hiroki Nagakura,Hiroki Nagakura,Wakana Iwakami,Wakana Iwakami,Hirotada Okawa,Hirotada Okawa,Shun Furusawa,Hideo Matsufuru,Kohsuke Sumiyoshi,Shoichi Yamada +10 more
TL;DR: In this article, the Boltzmann-radiation-hydrodynamics code is used to solve numerically the neutrino transfer and self-gravity simultaneously and consistently, and the collapse of a rotating core of the progenitor with a zero-age main-sequence mass of $11.2 and a shelluler rotation of $1.2.
Journal ArticleDOI
