A first-principles binary neutron star merger model of GW170817, GRB170817A, and AT2017gfo
Kenta Kiuchi, Sho Fujibayashi, Kota Hayashi +6
The multimessenger observation of the binary neutron star merger event GW170817, associated with its electromagnetic counterparts GRB170817A and AT2017gfo, marked a milestone in as…

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…

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…
