论文摘要
在本文中，我们提出了一种通过直接观察到地球月球二进制系统的直接观察来检测Sublunar Mass原始黑洞（PBH）的新方法。您的方法是基于将PBH视为一个扰动术语，假设PBH远离地球二进制（远大于1 au），而不是PBH（比PB的质量大于1 au），而不是PBH（比PB的质量小）。这种扰动处理使我们能够开发一个框架来计算诸如Earth-moon二进制系统之类的通用二元系统的轨道。我们的数值结果表明，地月距离对系统的初始值很敏感。在大多数情况下，PBH和地球系统之间的长期相互作用会诱导地球轨道上的持久烙印，并且这些烙印可以随着时间的流逝而积累，最终导致可观察到的偏差，可用于缩减PBH的性质。
In this paper we propose a new way to detect sublunar-mass primordial black holes (PBHs) by direct observations of the Earth-Moon binary system.Our method is based on treating PBH as a perturbation term, by assuming that the PBH is far away from the Earth-Moon binary (far greater than 1 AU) and the mass of the PBH is small (less than the lunar mass). This perturbation treatment allows us to develop a framework to calculate the orbits of a generic binary system such as the Earth-Moon binary system. Our numerical results show that the Earth-Moon distance is sensitive to the initial values of the system. In most cases, the long-duration interactions between the PBH and the Earth-Moon system can induce lasting imprints on the Earth-Moon's orbit, and these imprints can accumulate over time, eventually giving rise to observable deviations which can be used to infer the properties of the PBH.
