Validation of Radiative Transfer Computation with Monte Carlo Method for Ultra-Relativistic Background Flow
Ayako Ishii, Naofumi Ohnishi, Hiroki Nagakura +2
We developed a three-dimensional radiative transfer code for an ultra-relativistic background flow-field by using the Monte Carlo (MC) method in the context of gamma-ray burst (GRB…
Explosive nucleosynthesis in the neutrino-driven aspherical supernova explosion of a non-rotating 15 star with solar metallicity
Shin-ichiro Fujimoto, Kei Kotake, Masa-aki Hashimoto +2
We investigate explosive nucleosynthesis in a non-rotating 15 star with solar metallicity that explodes by a neutrino-heating supernova (SN) mechanism aided by both standi…
Effects of Rotation on Stochasticity of Gravitational Waves in Nonlinear Phase of Core-Collapse Supernovae
Kei Kotake, Wakana Iwakami Nakano, Naofumi Ohnishi
By performing three-dimensional (3D) simulations that demonstrate the neutrino-driven core-collapse supernovae aided by the standing accretion shock instability (SASI), we study ho…
Ray-Tracing Analysis of Anisotropic Neutrino Radiation for Estimating Gravitational Waves in Core-Collapse Supernovae
Kei Kotake, Wakana Iwakami, Naofumi Ohnishi +1
We propose a ray-tracing method to estimate gravitational waves (GWs) generated by anisotropic neutrino emission in supernova cores. To calculate the gravitational waveforms, we de…
Stochastic Nature of Gravitational Waves from Supernova Explosions with Standing Accretion Shock Instability
Kei Kotake, Wakana Iwakami, Naofumi Ohnishi +1
We study properties of gravitational waves based on the three-dimensional simulations, which demonstrate the neutrino-driven explosions aided by the standing accretion shock instab…
