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…
Collapse of rotating massive stars leading to black hole formation and energetic supernovae
Sho Fujibayashi, Yuichiro Sekiguchi, Masaru Shibata +1
We explore a possible scenario of the explosion as a result of core collapses of rotating massive stars that leave a black hole by performing a radiation-viscous-hydrodynamics simu…
Self-consistent picture of the mass ejection from a one second-long binary neutron star merger leaving a short-lived remnant in general-relativistic neutrino-radiation magnetohydrodynamic simulation
Kenta Kiuchi, Sho Fujibayashi, Kota Hayashi +3
We perform a general-relativistic neutrino-radiation magnetohydrodynamic simulation of a one second-long binary neutron star merger on Japanese supercomputer Fugaku using about $72…
A Monte-Carlo based relativistic radiation hydrodynamics code with a higher-order scheme
Kyohei Kawaguchi, Sho Fujibayashi, Masaru Shibata
We develop a new relativistic radiation hydrodynamics code based on the Monte-Carlo algorithm. In this code, we implement a new scheme to achieve the second-order accuracy in time…
Comprehensive study of mass ejection and nucleosynthesis in binary neutron star mergers leaving short-lived massive neutron stars
Sho Fujibayashi, Kenta Kiuchi, Shinya Wanajo +3
By performing general relativistic hydrodynamics simulations with an approximate neutrino-radiation transfer, the properties of ejecta in dynamical and post-merger phases are inves…
Electromagnetic counterparts of binary neutron star mergers leading to a strongly magnetized long-lived remnant neutron star
Kyohei Kawaguchi, Sho Fujibayashi, Kenta Hotokezaka +2
We explore the electromagnetic counterparts that will associate with binary neutron star mergers for the case that remnant massive neutron stars survive for s after…
