In rotating magnetospheres planted on compact objects, there usually exist lightcylinders (LC), beyond which the rotation speed of the magnetic field lines exceeds the speed of light. The LC is a close analog to the horizon in gravity, and is a casual boundary for charged particles that are restricted to move along the magnetic field lines. In this work, it is proposed that there should be Hawking-like radiation of charged particles from the LC of a rotating magnetosphere from the point of view of tunneling by using the field sheet metric.

通过隧道穿过旋转磁层的光柱，产生类似霍金的带电粒子辐射

在种植在致密物体上的旋转磁层中，通常存在光柱（LC），超过该光柱，磁力线的旋转速度超过光速。LC 与重力中的地平线非常相似，并且是限制沿磁场线移动的带电粒子的临时边界。在这项工作中，通过使用场表度量，从隧穿的角度提出了来自旋转磁层的 LC 的带电粒子的类霍金辐射。
