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…
Tayler-Spruit dynamo in binary neutron star merger remnants
Alexis Reboul-Salze, Paul Barrère, Kenta Kiuchi +4
In binary neutron star mergers, the remnant can be stabilized by differential rotation before it collapses into a black hole. Therefore, the angular momentum transport mechanisms a…
Variety of disc wind-driven explosions in massive rotating stars. II. Dependence on the progenitor
Ludovica Crosato Menegazzi, Sho Fujibayashi, Masaru Shibata +2
We assess the variance of supernova(SN)-like explosions associated with the core collapse of rotating massive stars into a black hole-accretion disc system under changes in the pro…
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…
Constraints of the maximum mass of quark stars based on post-merger evolutions
Yurui Zhou, Chen Zhang, Junjie Zhao +3
We semi-analytically investigate the post-merger evolution of the binary quark star merger. The effective-one-body method is employed to estimate the energy and angular momentum di…
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…
