Maeda-Dadhich Solutions as Real Black Holes

S. O. Alexeyev, B. N. Latosh, A. N. Petrov

摘要:

本文分析了文[3]-[6]中在Einstein-Gauss-Bonnet引力框架下Kaluza-Klein分裂的四维静态Schwarzschild型解。这些解中的物质是由辅助维度创造的。我们工作的主要目标是研究物理上可感知的特征,这是可以观察到的。对扰动方程的研究表明了它们在线性扰动下的稳定性。的参数的具体组合,允许构建黑洞状物体与一个或两个地平线或裸奇点的确定。这些黑洞周围的测试粒子的稳定轨道。当Hawking蒸发定律具有与通常广义相对论相反的行为时,我们给出了解的奇异性质。

英文摘要:

A four-dimensional static Schwarzschild-like solution obtained in [3]-[6] in the frames of the Einstein-Gauss-Bonnet gravity at the Kaluza-Klein split is analyzed. The matter in these solutions is created by auxiliary dimensions. The main goal of our work is to study physically sensible characteristics, which could be observable. Study of the perturbed equations demonstrates their stability under linear perturbations. The specific combinations of the parameters, permitting to construct black hole-like objects with one or two horizons or naked singularities are determined. Stable orbits of test particles around these black holes are presented. We show the exotic thermodynamical properties of the solution, when the Hawking evaporation law has the behavior opposite to usual one in General Relativity.
