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…

Outflow energy and black-hole spin evolution in collapsar scenarios

Masaru Shibata, Sho Fujibayashi, Alan Tsz-Lok Lam +2

We explore the collapsar scenario for long gamma-ray bursts by performing axisymmetric neutrino-radiation magnetohydrodynamics simulations in full general relativity for the first…

Supernova-like explosion of massive rotating stars from disks surrounding a black hole

Sho Fujibayashi, Alan Tsz-Lok Lam, Masaru Shibata +1

We perform a new general-relativistic viscous-radiation hydrodynamics simulation for supernova-like explosion associated with stellar core collapse of rotating massive stars to a s…

Kilonovae of binary neutron star mergers leading to short-lived remnant neutron star formation

Kyohei Kawaguchi, Sho Fujibayashi, Nanae Domoto +3

We study kilonova emission from binary neutron star (BNS) mergers for the case that a remnant massive neutron star (MNS) forms and collapses to a black hole within ms after th…
