Vachaspati 2007 暗星作为伽玛暴的前身星

主要内容:
正在塌缩成黑洞并处于史瓦西视界内的星称为暗星,作者认为碰撞的暗星可以爆发出伽玛暴。
(但是暗星的时标应该很短,谁会和它碰撞呢)

Stars that are collapsing toward forming a black hole but are frozen near the Schwarzschild horizon are termed ``black stars''. Collisions of black stars, in contrast to black hole collisions, may be sources of gamma ray bursts, whose basic parameters are estimated quite simply and are found to be consistent with observed gamma ray bursts. Black star gamma ray bursts should be preceded by gravitational wave emission similar to that from the coalescence of black holes.
