Nucleosynthesis in the Accretion-induced Collapse of magnetised, Rotating White Dwarfs

Laurenz Thümmler, Takami Kuroda, Masaru Shibata

Accretion-induced collapse (AIC) of a rotating oxygen-neon-magnesium white dwarf (WD) is an alternative channel of neutron-star formation, in which a mass-accreting star near the C…

The hydrodynamics of stratified ultra-relativistic outflows and the origin of GRB X-ray plateaus

Gilad Sadeh, Kenta Hotokezaka, Masaru Shibata

The origin of the X-ray plateau phase observed in a large fraction of gamma-ray burst afterglows remains debated. We present a novel analytic framework for the hydrodynamics of ult…

A formation scenario of black hole-envelope systems --viscous hydrodynamics simulation in general relativity--

Alan Tsz Lok Lam, Masaru Shibata, Kenta Hotokezaka +1

By performing a viscous hydrodynamics simulation in general relativity for super-Eddington accretion flows onto massive black holes of mass --, we discuss a fo…

Accretion-powered flares from black hole-disk collisions in galactic nuclei

Joaquin Pelle, Kyohei Kawaguchi, Masaru Shibata +1

Black hole impacts on accretion disks in galactic nuclei can power luminous transients, but predicting their observable signatures is challenging because the post-collision flow is…

Collapse of rotating very massive stellar cores leading to a black hole and a massive disk as a source of gravitational waves

Masaru Shibata, Sho Fujibayashi

We derive models of rotating very massive stellar cores with mass -- which are marginally stable to the pair-unstable collapse, assuming that the core is…

Neutrino pair annihilation driven jets from black-hole torus systems

Kyohei Kawaguchi, Sho Fujibayashi, Masaru Shibata

We perform axisymmetric general relativistic radiation-viscous hydrodynamics simulations of black hole (BH)-torus systems with full Boltzmann Monte-Carlo neutrino transport to inve…
