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…
Extending the infrastructure of the BAM code towards resistive general-relativistic magnetohydrodynamics: tests and first applications
Matthew Beaudoin, Maximilano Ujevic, Ramon Jaeger +4
Many astrophysical phenomena, including pulsars and short gamma-ray bursts, are associated with the extremely strong magnetic fields present in neutron stars and neutron star merge…
SACRA-K: A Performance-Portable Numerical Relativity Code with Kokkos
Ming-Zhe Han, Kenta Kiuchi, Masaru Shibata
We present SACRA-K (SimulAtor for Compact objects in Relativistic Astrophysics with Kokkos), a performance-portable numerical relativity code ported from the Fortran code SACRA-MPI…
Subsolar-mass binary mergers of strange stars and neutron stars: gravitational waves and ejecta
Yong Gao, Ming-Zhe Han, Kenta Kiuchi +3
We present the first numerical-relativity simulations of subsolar-mass binary strange star (SS) mergers and compare with binary neutron star (NS) mergers across equations of state,…
Implementation of multi-grid Poisson solver in numerical relativity and its application to gravitational collapse of massive star
Kenta Kiuchi, Hirotada Okawa
We develop a new grid-based multi-grid Poisson solver in numerical relativity. We report the performance of the multi-grid Poisson solver in the initial value problems for two-punc…
A magnetar formation in binary neutron star merger
Kenta Kiuchi, Alexis Reboul-Salze, Yuichiro Sekiguchi +1
We conduct a global general relativistic neutrino-radiation-transfer magnetohydrodynamics simulation of a - binary neutron star with the unprecedented spatial re…
