Kilonova Emission from Black Hole–Neutron Star Mergers: Observational Signatures of Anisotropic Mass Ejection
Kilonova Emission from Black Hole–Neutron Star Mergers: Observational Signatures of Anisotropic Mass Ejection
The gravitational wave event GW170817 associated with the short gamma-ray burst (GRB) 170817A confirms that binary neutron star (BNS) mergers are one of the origins of short GRBs. The associated kilonova emission, radioactively powered by nucleosynthesized heavy elements, was also detected. Black hole-neutron star (BH-NS) mergers have been argued to …
