论文摘要
我们研究了通过张量真空满足爱因斯坦方程的静态黑洞溶液的扩展重力解耦方法。来源具有相当通用的特征，并满足了强大的能量条件。通过应用Newman-Janis和Azreg-Aïnou算法获得静态度量的固定轴对称对应物。研究了旋转溶液的热力学，并得出了各种热力学量的表达。研究温度，自由能和特定热量在地平线半径上的依赖性，以获取毛茸茸的参数和黑洞自旋的各种值。这样的研究表明，与大毛的黑色孔相比，小毛的黑色孔在热力学上更加稳定，并且地平线半径和温度范围可以在热力学平衡中以旋转的毛茸茸的黑洞在周围的环境中取决于毛发参数。我们进一步讨论了黑洞热力学的第一定律，并讨论其含义。
We study the method of extended gravitational decoupling in obtaining static black hole solutions satisfying Einstein's equations with a tensor vacuum. The source has quite generic characteristics and satisfies the strong energy condition. The stationary, axisymmetric counterpart of the static metric is obtained by applying the Newman-Janis and Azreg-Aïnou algorithms. The thermodynamics of the rotating solution is studied and the expressions of various thermodynamic quantities are derived. The dependence of the temperature, free energy and specific heat on the horizon radius is studied for various values of the hairy parameter and the black hole spin. Such a study reveals that small hairy black holes are thermodynamically more stable compared to large hairy black holes, and that the horizon radius and temperature range for which the rotating hairy black holes can be in thermodynamic equilibrium with the surroundings depends non-trivially on the hairy parameters. We further discuss the first law of black hole thermodynamics for the hairy case and discuss its implications.
