Gravitational waves from spinning black hole-neutron star binaries: dependence on black hole spins and on neutron star equations of state
Koutarou Kyutoku, Hirotada Okawa, Masaru Shibata +1
We study the merger of black hole (BH)-neutron star (NS) binaries with a variety of BH spins aligned or anti-aligned with the orbital angular momentum, and with the mass ratio in t…
Extracting equation of state parameters from black hole-neutron star mergers. I. Nonspinning black holes
Benjamin D. Lackey, Koutarou Kyutoku, Masaru Shibata +2
The late inspiral, merger, and ringdown of a black hole-neutron star (BHNS) system can provide information about the neutron-star equation of state (EOS). Candidate EOSs can be app…
Gravitational waves and neutrino emission from the merger of binary neutron stars
Yuichiro Sekiguchi, Kenta Kiuchi, Koutarou Kyutoku +1
Numerical simulations for the merger of binary neutron stars are performed in full general relativity incorporating a finite-temperature (Shen's) equation of state (EOS) and neutri…
Binary Neutron Star Mergers: Dependence on the Nuclear Equation of State
Kenta Hotokezaka, Koutarou Kyutoku, Hirotada Okawa +2
We perform a numerical-relativity simulation for the merger of binary neutron stars with 6 nuclear-theory-based equations of state (EOSs) described by piecewise polytropes. Our pur…
