摘要

在这项工作中，我们通过分析陀螺仪沿时间曲线传输的行为来研究静态球对称Reissner-Nordström事件视界和裸奇点。我们发现，只要轨迹是类时的，黑洞和裸奇点的进动频率都是有限的。我们的目标是量化在接近视界和裸奇点时陀螺仪进动行为的差异。此外，我们通过检查进动频率的反转，探索了区分视界和裸奇点的可能性。

Gyroscopic precession in Reissner–Nordström spacetime

In this work, we investigate a static spherically symmetric Reissner–Nordström event horizon and a naked singularity by analyzing the behavior of a gyroscope transported along a timelike curve. We find that the precession frequency remains finite for both the black hole and the naked singularity as long as the trajectory is timelike. Our objective is to quantify the differences in the gyroscope’s precession behavior when approaching an event horizon versus a naked singularity. Additionally, we explore the potential for distinguishing between an event horizon and a naked singularity by examining the reversal of the precession frequency.
