论文摘要
在双中性恒星（NS）或NS-Black孔系统的晚期灵感阶段中，其中一个NS是磁场，随着二进制的接近，其同伴产生的磁力上的潮汐力将大大增加。潮汐诱导的变形可能会超过磁盘的外壳在合并之前仅维持几秒钟或子代数的最大值。因此，可能会发生灾难性的全球地壳破坏，并且磁力内部装饰中存储的磁能将有机会释放，这将被视为一种超过100倍的超叶状，其大于磁铁的巨型耀斑。这种机制自然可以解释最近观察到的GRB 211211a的前体，包括其准二旋振荡。我们预测，在即将到来的重力波O4/O5时期，可能会有一小部分与此类超级耀斑相关的双NS合并。如果观察到，可以获得有关NS内部结构和磁场的大量信息，这很难在其他地方研究。
In the late inspiral phase of a double neutron star (NS) or NS-black hole system in which one NS is a magnetar, the tidal force on the magnetar arisen from its companion will increase dramatically as the binary approaches. The tidal-induced deformation may surpass the maximum that the magnetar's crust can sustain just seconds or subseconds before the coalescence. A catastrophic global crust destruction may thus occur, and the magnetic energy stored in the magnetar's interior will have the opportunity to be released, which would be observed as a superflare with energy 100s of times larger than giant flares of magnetars. Such a mechanism can naturally explain the recently observed precursor of GRB 211211A, including its quasiperiodic oscillation. We predict that in the coming gravitational wave O4/O5 period, there could be a fraction of detected double NS mergers associated with such super flares. If observed, copious information on the structure and magnetic field in an NS interior can be obtained, which is hard to study elsewhere.
