关于多毛黑洞的温度

On the temperature of hairy black holes

Vitalii Vertogradov, Dmitriy Kudryavcev

摘要:

引力解耦方法是一个非常有用的工具,通过最小的几何变形获得新的爱因斯坦方程的解决方案。本文考虑由引力退耦得到的带电毛状黑洞,计算了它们的Hawking温度,并与忽略毛状的情况进行了比较。我们发现,在一定的黑洞参数条件下,黑洞的毛会影响Hawking温度,使之升高,并且发现在毛的情况下,黑洞的温度与电荷无关。

英文摘要:

The gravitational decoupling method represents an extremely useful tool to obtain new solutions of the Einstein equations through minimal geometrical deformations. In this paper, we consider the hairy charged black hole obtained by the gravitational decoupling and calculate their Hawking temperature in order to compare it with the case when the hairs are ignored. We have found out that the hairs, under some conditions of black hole parameters, affect the Hawking temperature and can increase it. We have also found out that the black hole temperature, in hairy case, doesn't depend on the electric charge.
