论文摘要
我们研究了Vaidya时空上的鹰辐射，并进行重力崩溃，然后蒸发。崩溃的身体是一个无效的薄壳，蒸发是由负能量崩溃的零壳诱导的。这模仿了霍金辐射的后反应。使用Hawking的原始Bogoliubov转换方法，我们表征了辐射光谱，其由热发射以增加有效温度为主。我们计算此时间依赖温度，并找到与其他技术获得的结果相关的数值一致。蒸发时间的已知差异通过有效温度的不同性质来解释。作为一致性检查，我们从残余BH方案的零质量限制中重新介绍了结果。
We study Hawking radiation on a Vaidya space-time with a gravitational collapse followed by evaporation. The collapsing body is a null thin-shell and the evaporation is induced by a negative energy collapsing null-shell. This mimics the back-reaction to the Hawking radiation. Using Hawking's original method of Bogoliubov transformations we characterize the radiated spectrum as dominated by a thermal emission with an increasing effective temperature. We compute this time dependent temperature and find numerical agreement with results obtained by other techniques. The known divergences at the evaporation time are explained by the divergent nature of the effective temperature. As a consistency check, we re-derived the results from a zero mass limit of a remnant BH scenario.
