Going out with a bang: compact object collisions resulting from supernovae in binary systems
Abstract
Binary star systems containing a neutron star or a black hole with an evolved, massive star are dynamically perturbed when the latter undergoes a supernova explosion. It is possible that the natal kick received by the newly-formed neutron star in the supernova may place the stellar remnants into a bound, highly eccentric orbit. In this case, the two compact objects can tidally interact and spiral into one another on a short timescale. The interaction with an accretion disc of supernova debris is also considered. We quantify the likelihood of such events and show that they would be expected to produce a high-energy transient, possibly a short gamma-ray burst, typically within a few days of the supernova.
