论文摘要
在二元中子星（BNS）合并中形成的残留物的合并后重力波（GW）辐射尚未直接测量。我们在这项工作中表明，涉及GW170817的BN的性质，还受到PSR J0030+0451的限制，非旋转中子星（NS）的最大重力质量和某些核数据的下限是有利于合并后GW GW强的强GW辐射。该结论也适用于银河BNS系统的合并。还首选合并后的GW辐射，以提高从GW170817/GRB170817A/AT2017GFO与最新的脉冲质量测量值推断的非旋转NS的最大重力质量之间的一致性。预计在未来十年中，先进的Ligo/处女座探测器可以检测到GW170817样事件的突出合并后重力辐射，然后以极高的密度在物质的性质上散发出宝贵的灯光。
The post-merger gravitational wave (GW) radiation of the remnant formed in the binary neutron star (BNS) coalescence has not been directly measured, yet. We show in this work that the properties of the BNS involved in GW170817, additionally constrained by PSR J0030+0451, the lower limit on the maximum gravitational mass of non-rotating neutron star (NS) and some nuclear data, are in favor of strong post-merger GW radiation. This conclusion applies to the mergers of Galactic BNS systems as well. Significant post-merger GW radiation is also preferred to improve the consistency between the maximum gravitational mass of the non-rotating NS inferred from GW170817/GRB170817A/AT2017gfo and the latest mass measurements of pulsars. The prominent post-merger gravitational radiation of GW170817-like events are expected to be detectable by advanced LIGO/Virgo detectors in the next decade and then shed valuable lights on the properties of the matter in the extremely high density.
