AI 中文总结

本文提出双荷辛普森-维瑟黑洞反弹时空作为广义相对论精确解,由爱因斯坦星团与电磁场共同提供源项,实现正则黑洞时空。

AI 中文摘要

本文中,我们将带有电性和磁性电荷的辛普森-维瑟黑洞反弹(SV-BB)时空(即双荷SV-BB)呈现为广义相对论与麦克斯韦电动力学及径向压力为零的各向异性流体耦合的精确解。我们假设该各向异性流体代表一个爱因斯坦星团,它由大量沿圆形轨道运动的粒子组成的致密系统构成,这些粒子仅产生切向压力而径向压力为零。我们证明,双荷SV-BB度规(提供正则黑洞时空)可以作为爱因斯坦场方程的精确解获得,其源项由爱因斯坦星团(负责提供维持黑洞反弹喉部开放所需的奇异物质)与麦克斯韦电动力学框架下的电磁场组合而成。

英文摘要

In this work, we present the Simpson-Visser black-bounce (SV-BB) spacetime with both electric and magnetic charges (the dyonic SV-BB) as an exact solution of general relativity coupled to Maxwell electrodynamics and an anisotropic fluid with vanishing radial pressure. We assume the anisotropic fluid represents an Einstein cluster, which consists of a dense system of particles moving in circular orbits that generate only tangential pressure and zero radial pressure. We show that the dyonic SV-BB metric, which provides a regular black hole spacetime, can be obtained as an exact solution to the Einstein field equations sourced by a combination of an Einstein cluster (which is responsible for providing the exotic matter required to keep a black-bounce throat open) and an electromagnetic field in the framework of Maxwell electrodynamics.
