论文摘要
原始黑洞与中子星的碰撞导致黑洞最终消耗了整个中子星。但是,如果黑洞充满了磁性电,因此通过鹰辐射降低了衰减,则后果可能会大不相同。与中子恒星碰撞后,磁性黑洞非常迅速地停止。对于足够大的磁性电荷,我们表明可以检测到这种碰撞是中子恒星的旋转期突然变化,该碰撞是一个小故障或抗glitch。我们认为,磁性原始黑洞然后将其沉降到中子恒星的核心,并不一定会吞噬整个中子星。该系统可以达到长寿,准稳定的平衡。由于黑洞与中子恒星相比是微观的,因此与碰撞之前相比,大多数恒星特性保持不变。但是,中子恒星将加热,其表面磁场可能会改变,这两种影响都可能可观察到。
The collision of a primordial black hole with a neutron star results in the black hole eventually consuming the entire neutron star. However, if the black hole is magnetically charged, and therefore stable against decay by Hawking radiation, the consequences can be quite different. Upon colliding with a neutron star, a magnetic black hole very rapidly comes to a stop. For large enough magnetic charge, we show that this collision can be detected as a sudden change in the rotation period of the neutron star, a glitch or anti-glitch.We argue that the magnetic primordial black hole, which then settles to the core of the neutron star, does not necessarily devour the entire neutron star; the system can instead reach a long-lived, quasi-stable equilibrium. Because the black hole is microscopic compared to the neutron star, most stellar properties remain unchanged compared to before the collision. However, the neutron star will heat up and its surface magnetic field could potentially change, both effects potentially observable.
