Pre-merger localization of eccentric compact binary coalescences with second-generation gravitational-wave detector networks
Koutarou Kyutoku, Naoki Seto
We study the possibility of pre-merger localization of eccentric compact binary coalescences by second-generation gravitational-wave detector networks. Gravitational waves from ecc…
Radioactively Powered Emission from Black Hole-Neutron Star Mergers
Masaomi Tanaka, Kenta Hotokezaka, Koutarou Kyutoku +4
Detection of electromagnetic counterparts of gravitational wave (GW) sources is important to unveil the nature of compact binary coalescences. We perform three-dimensional, time-de…
Progenitor models of the electromagnetic transient associated with the short GRB 130603B
Kenta Hotokezaka, Koutarou Kyutoku, Masaomi Tanaka +4
An electromagnetic transient powered by the radioactive decay of r-process elements, a so-called kilonova/macronova, is one of the possible observable consequences of compact binar…
High-Energy Radiation from Remnants of Neutron Star Binary Mergers
Hajime Takami, Koutarou Kyutoku, Kunihito Ioka
We study high-energy emission from the mergers of neutron star binaries as electromagnetic counterparts to gravitational waves aside from short gamma-ray bursts. The mergers entail…
Remnant massive neutron stars of binary neutron star mergers: Evolution process and gravitational waveform
Kenta Hotokezaka, Kenta Kiuchi, Koutarou Kyutoku +4
Massive (hypermassive and supramassive) neutron stars are likely to be often formed after the merger of binary neutron stars. We explore the evolution process of the remnant massiv…
Nonspinning black hole-neutron star mergers: a model for the amplitude of gravitational waveforms
Francesco Pannarale, Emanuele Berti, Koutarou Kyutoku +1
Black hole-neutron star binary mergers display a much richer phenomenology than black hole-black hole mergers, even in the relatively simple case - considered in this paper - in wh…
