Long-term Monte Carlo-based neutrino-radiation hydrodynamics simulations for a black hole-torus system
Kyohei Kawaguchi, Sho Fujibayashi, Masaru Shibata
We present our new general relativistic Monte Carlo (MC)-based neutrino radiation hydrodynamics code designed to solve axisymmetric systems with several improvements. The main impr…
Threshold mass of the general relativistic instability for supermassive star cores
Masaru Shibata, Sho Fujibayashi, Cédric Jockel +1
The dependence of the final fate of supermassive star (SMS) cores on their mass and angular momentum is studied with simple modeling. SMS cores in the hydrogen burning phase encoun…
Powerful explosions from the collapse of rotating supermassive stars
Sho Fujibayashi, Cédric Jockel, Kyohei Kawaguchi +2
We perform new general relativistic hydrodynamics simulations for collapses of rotating supermassive star cores with an approximate nuclear burning up to carbon and a detailed equa…
GRB 211211A: The Case for an Engine Powered over r-Process Powered Blue Kilonova
Hamid Hamidani, Masaomi Tanaka, Shigeo S. Kimura +2
The recent Gamma-Ray Burst (GRB) GRB 211211A provides the earliest ( h) data of a kilonova (KN) event, displaying bright ( erg s) and blue early emissio…
Black hole-neutron star mergers with massive neutron stars in numerical relativity
Shichuan Chen, Luohan Wang, Kota Hayashi +3
We study the merger of black hole-neutron star (BH-NS) binaries in numerical relativity, focusing on the properties of the remnant disk and the ejecta, varying the mass of compactn…
Three dimensional end-to-end simulation for kilonova emission from a black-hole neutron-star merger
Kyohei Kawaguchi, Nanae Domoto, Sho Fujibayashi +5
We study long-term evolution of the matter ejected in a black-hole neutron-star (BH-NS) merger employing the results of a long-term numerical-relativity simulation and nucleosynthe…
