论文摘要
最近，已经发现并发现具有多个光子球的渐近式黑色孔会产生独特的观察性特征。在本文中，我们关注这些黑洞解决方案是否在物理上可行，例如满足感兴趣的能量条件。有趣的是，具有两个光子球的黑洞和赤裸裸的奇异溶液在物理合理的模型中显示出一个符合零，弱，弱，主导和强的能量条件的模型中存在。我们的发现表明，具有多个光子球体的黑洞可能并不频繁，但它们不是异国情调的。
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.
