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,…
Dependence of postmerger properties on the thermal heating efficiency in neutron star mergers
Ming-Zhe Han, Yong Gao, Kenta Kiuchi +1
We systematically perform numerical-relativity simulations for equal-mass binary neutron star mergers for the models varying the thermal index with three different eq…
Upper Limit of Sound Speed in Nuclear Matter: A Harmonious Interplay of Transport Calculation and Perturbative Quantum Chromodynamic Constraint
Shao-Peng Tang, Yong-Jia Huang, Ming-Zhe Han +1
Very recently, it has been shown that there is an upper bound on the squared sound speed of nuclear matter from the transport, which reads . In this work, w…
