摘要

短硬伽马射线暴(SHB) 170817A紧随引力波(GWs)探测到的第一次中子星合并(NSM)之后，毫无疑问地表明NSM产生了SHB。它的低亮度和其他不同于普通shb的特性，是用相对较近的shb的grb炮弹模型预测的，这些shb几乎完全是低亮度的shb。这些离轴很远的低光度shb大多是附近nsm的确凿证据，就像Ligo-Virgo探测到的那样。更遥远的nsm的确凿证据是PWN的余辉，由新生的n*s的自旋下降提供动力，在可见的SHB之前，或者在从地球发射出去的不可见的SHB之前。

The Smoking Guns Of Neutron Stars Mergers

The short hard gamma ray burst (SHB) 170817A that followed the first neutron stars merger (NSM) detected in gravitational waves (GWs) has shown beyond doubt that NSMs produce SHBs. Its low luminosity and other properties that differ from those of ordinary SHBs, were predicted by the cannonball model of GRBs for relatively nearby SHBs, which almost entirely are low luminosity SHBs viewed from far off-axis. Such far off-axis low luminosity SHBs are mostly the smoking guns of only nearby NSMs, like those detectable by Ligo-Virgo. The smoking guns of much more distant NSMs are PWN afterglows powered by the spin-down of the nascent n*s, preceded by a visible SHB, or by an invisible SHB, which is beamed away from Earth.

期刊介绍： La Rivista del Nuovo Cimento is an international peer-reviewed journal. It publishes monographs in all fields of physics. These monographies aim at presenting the state of the art of topical subjects of relevant interest for the community. Usually, authors are invited and topics suggested by the Deputy Editors-in-Chief, but also spontaneous submissions are examined.
