AI总结:

本文研究了具有多个光子球的黑洞解的物理可行性,发现在满足零、弱、主和强能量条件的物理合理模型中存在此类解,表明它们虽不常见但并非奇异。

摘要:

最近,具有多个光子球的渐近平坦黑洞被发现,并产生独特的观测特征。本文关注这些黑洞解是否具有物理可行性,例如满足相关能量条件。有趣的是,在满足零、弱、主和强能量条件的物理合理模型中,存在具有两个光子球和一个反光子球的黑洞与裸奇点解。研究结果表明,具有多个光子球的黑洞可能不常见,但并非奇异。

英文摘要:

Recently, asymptotically-flat black holes with multiple photon spheres have been discovered and found to produce distinctive observational signatures. In this paper, we focus on whether these black hole solutions are physically viable, e.g., satisfying energy conditions of interest. Intriguingly, black hole and naked singularity solutions with two photon spheres and one anti-photon sphere are shown to exist in physically reasonable models, which satisfy the null, weak, dominant and strong energy conditions. Our findings reveal that black holes with multiple photon spheres may not be frequent, but they are not exotic.
