Convective stability analysis of massive neutron stars formed in binary mergers
Yong Gao, Kota Hayashi, Kenta Kiuchi +3
We perform fully general-relativistic hydrodynamics simulations of binary neutron star mergers over post-merger to investigate the dynamics of remnant massive neutron…
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…
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…
Actinide-boosting r Process in Black Hole-Neutron Star Merger Ejecta
Shinya Wanajo, Sho Fujibayashi, Kota Hayashi +3
We examine nucleosynthesis in the ejecta of black hole-neutron star mergers based on the results of long-term neutrino-radiation-magnetohydrodynamics simulations for the first time…
Jet from binary neutron star merger with prompt black hole formation
Kota Hayashi, Kenta Kiuchi, Koutarou Kyutoku +2
We performed the longest numerical-relativity neutrino-radiation magnetohydrodynamics simulation for a binary neutron star merger that extends to after the…
