超新星激波撞击中子星磁层的可能观测现象
On the possible observational manifestation of supernova shock impact on the neutron star magnetosphere
摘要：
研究了大质量双星系统中超新星爆发对中子星磁层的影响。超新星激波撞击充满等离子体的NS磁层，可以导致具有显著磁能的磁层尾的形成。形成的电流片中的磁场重联可以将储存在尾部的磁能转化为加速带电粒子的动能。由相对论粒子束激发的等离子体不稳定性可能导致相干射电发射的短脉冲的形成，其参数与观测到的明亮的河外毫秒射电爆发相似（Lorimer等人，2007年）。
英文摘要：
Impact of supernova explosion on the neutron star magnetosphere in a massive binary system is considered. The supernova shock striking the NS magnetosphere filled with plasma can lead to the formation of a magnetospheric tail with significant magnetic energy. The magnetic field reconnection in the current sheet formed can convert the magnetic energy stored in the tail into kinetic energy of accelerated charged particles. Plasma instabilities excited by beams of relativistic particles can lead to the formation of a short pulse of coherent radio emission with parameters similar to those of the observed bright extragalactic millisecond radio burst (Lorimer et al. 2007).
