关于Vaidya解中陷曲面的一个注记

A Note on trapped Surfaces in the Vaidya Solution

Ingemar Bengtsson, José M. M. Senovilla

摘要:

Vaidya解描述了非相干辐射的有限壳层落入平坦时空并产生史瓦西黑洞的引力坍缩。有一个问题,封闭的捕获表面是否可以延伸到平坦区域(而封闭的外部捕获表面当然可以)。对于自相似坍缩的特殊情况,我们证明了答案是肯定的,当且仅当质量函数上升得足够快。

英文摘要:

The Vaidya solution describes the gravitational collapse of a finite shell of incoherent radiation falling into flat spacetime and giving rise to a Schwarzschild black hole. There has been a question whether closed trapped surfaces can extend into the flat region (whereas closed outer trapped surfaces certainly can). For the special case of self-similar collapse we show that the answer is yes, if and only if the mass function rises fast enough.
