A supernova remnant associated with a nascent black hole low-mass X-ray binary
arXiv:2010.15341
Abstract
Energy released when the core of a high-mass star collapses into a black hole often powers an explosion that creates a supernova remnant. Black holes have limited windows of observability, and consequently are rarely identified in association with supernova remnants. Analysing multi-messenger data, we show that MAXI J1535-571 is the black hole produced in the stellar explosion that gave rise to the supernova remnant G323.7-1.0, making it the first case of an association between a black hole low-mass X-ray binary and a supernova remnant. Given this connection, we can infer from our modelling that the progenitor system was a close binary whose primary star had an initial mass of approx. 23-35 solar masses with a companion star about 10 times less massive.
