共形引力中带电黑洞的形成和蒸发

Formation and evaporation of an electrically charged black hole in conformal gravity

Cosimo Bambi, Leonardo Modesto, Shiladitya Porey, Leslaw Rachwal

摘要:

本文推广了以往关于共形引力下黑洞的形成和蒸发的工作,研究了球对称带电辐射薄壳的引力坍缩。这个过程创造了一个无奇点的黑洞。假设在蒸发过程中电荷$Q$是恒定的,蒸发的最终产物是具有$M=Q$的极值剩余,其在无限时间量内达到。我们还讨论了外尔共形引力下黑洞的奇异性和热力学问题。

英文摘要:

Extending previous work on the formation and the evaporation of black holes in conformal gravity, in the present paper we study the gravitational collapse of a spherically symmetric and electrically charged thin shell of radiation. The process creates a singularity-free black hole. Assuming that in the evaporation process the charge $Q$ is constant, the final product of the evaporation is an extremal remnant with $M=Q$, which is reached in an infinite amount of time. We also discuss the issue of singularity and thermodynamics of black holes in Weyl's conformal gravity.
