短伽玛射线暴(SGRB)余辉光变曲线中的喷流中断,迄今为止很少被探测到,对于估算喷出物的半张角(θ j)以及中子星星合并率至关重要。本文报道了GRB 150424 A和GRB 160821 B中喷流衰减行为的探测,发现θ j <$0.1 rad。加上2015年之前报道的五个事件和最近”发现”的另外三个事件(GRB 050709,GRB 060614和GRB 140903 A),我们有一个由九个SGRB和一个长短GRB组成的样本,其θ j估计合理。特别是,样本中的三个Swift爆发的红移z≤ 0.2,我们估计本地中子星星合并率密度为
The jet breaks in the afterglow light curves of short gamma-ray bursts (SGRBs), rarely detected so far, are crucial for estimating the half-opening angles of the ejecta (θ j) and hence the neutron star merger rate. In this work, we report the detection of jet decline behaviors in GRB 150424A and GRB 160821B, and find θ j∼ 0.1 rad. Together with five events reported before 2015 and three others" identified" recently (GRB 050709, GRB 060614, and GRB 140903A), we have a sample consisting of nine SGRBs and one long-short GRB with reasonably estimated θ j. In particular, three Swift bursts in the sample have redshifts z≤ 0.2, with which we estimate the local neutron star merger rate density to be
