论文摘要
尊重无扭矩系统的角动量保存,自然要考虑旋转大量物体的旋转解决方案。除此之外,以旋转的真实天体物理黑洞的驱动,我们使用纽曼 - 贾尼斯形式主义来构建常规的旋转黑洞。我们从标准一般相对论框架的框架中的非线性定期静态黑洞开始,然后通过这种形式主义获得相关的旋转解决方案。我们通过研究Ergosphere的边界来研究度量的几何特性。我们还分析了ADS时空中溶液的热力学特性,并检查热稳定性和可能的相变。此外,我们使用真正的无质量标量场作为研究其动态稳定性的探针来扰动黑洞。我们获得了准频率的真实和虚构部分的分析表达。最后,我们在艾科尼尔极限中寻找准频率和光子球体的性质之间的连接。
Respecting the angular momentum conservation of torque-free systems, it is natural to consider rotating solutions of massive objects. Besides that, motivated by the realistic astrophysical black holes that rotate, we use the Newman-Janis formalism to construct a regular rotating black hole. We start with a nonlinearly charged regular static black hole in the framework of the standard general relativity and then obtain the associated rotating solution through such a formalism. We investigate the geometrical properties of the metric by studying the boundary of ergosphere. We also analyze thermodynamic properties of the solution in AdS spacetime and examine thermal stability and possible phase transition. In addition, we perturb the black hole by using of a real massless scalar field as a probe to investigate its dynamic stability. We obtain an analytic expression for the real and imaginary parts of the quasinormal frequencies. Finally, we look for a connection between the quasinormal frequencies and the properties of the photon sphere in the eikonal limit.
