Hawking radiation in a dynamical Kerr black hole using a new tortoise coordinate

摘要: 本文用一种新的乌龟坐标变换和改进的Damour-Ruffini方法研究了动态Kerr黑洞的Hawking辐射,得到了随时间和纬度角而变化的局域温度和具有准黑体谱形式的Hawking辐射谱.其结果与采用通常的乌龟坐标变换所得结果有所不同,而通常的乌龟坐标变换在量纲上存在一定的问题,本文的结果也许更为合理.

Abstract: Hawking radiation from a dynamical Kerr black hole is investigated using a new tortoise coordinate and the improved Damour-Ruffini method. The local temperature changing with time and latitude angle and the Hawking radiation with quasi-blackbody spectrum are obtained. The present results are different from the existing results obtained by using usual tortoise coordinate. There exists a certain problem in dimension for the usual tortoise coordinate and the present results may be more reasonable. -
