Description

The dual detection of a short gamma-ray burst (GRB 170817A) (Goldstein et al., 2017) and a gravitational wave (GW170817) (Abbott et al., 2017) signal marked the first direct confirmation that both phenomena can originate from the same astrophysical event. While the GW and SGRB signals give valuable insights into the properties of the merging neutron stars, they offer little information about the binary system's evolutionary history before the merger. This study examines the effect of extreme mass transfer to the NS during the ULX phase on the DNS system's final state and the SGRB jet's emergence.
