碰撞引起的毛刺/抗毛刺

Collision-Induced Glitch/Anti-Glitches

Y. F. Huang, J. J. Geng, Z. B. Zhang

摘要:

我们认为,一个小的固体与脉冲星的碰撞可能会导致一个可观察到的毛刺/反毛刺。毛刺幅度取决于小物体的质量和碰撞参量。在碰撞中,相当数量的势能将以短的硬X射线爆发或相对持久的软X射线余辉的形式释放。毛刺幅度和X射线能量学之间的联系可以帮助诊断这些时序异常的性质。

英文摘要:

We suggest that the collision of a small solid body with a pulsar can lead to an observable glitch/anti-glitch. The glitch amplitude depends on the mass of the small body and the impact parameter as well. In the collision, a considerable amount of potential energy will be released either in the form of a short hard X-ray burst or as a relatively long-lasting soft X-ray afterglow. The connection between the glitch amplitude and the X-ray energetics can help to diagnose the nature of these timing anomalies.
