论文摘要
由两个中子星（BNS）组成的近距离二进制系统发射引力波，使它们可以比哈勃时间短的时间表合并。人们普遍认为，此类系统中的NS-NS合并功率短伽马射线爆发（GRB）。已经提出了几种可能导致电磁能在合并之前释放的机制。我们估计有能力观察光谱 - 罗根 - 伽马望远镜可能产生的爆发前发射。我们还研究了第一个此类事件，GRB210919A，该事件落入了爆发前不到两天的SRG望远镜的视野。
Close binary systems consisting of two neutron stars (BNS) emit gravitational waves, that allow them to merge on timescales shorter than Hubble time. It is widely believed, that NS-NS mergers in such systems power short gamma-ray bursts (GRB). Several mechanisms which could lead to electromagnetic energy release prior to a merger have been proposed. We estimate the ability to observe the possible pre-burst emission with telescopes of Spectrum-Roentgen-Gamma. We also investigate first such event, GRB210919A, which fell into the field of view of the SRG telescopes less than two days before the burst.
