我们通过研究 Randall-Sundrum 型膜上的奥本海默-斯奈德式塌缩来研究膜世界引力如何影响引力塌缩和黑洞形成。在不对体积做出任何假设的情况下,我们证明了膜上的外部时空是非静态的。在没有物质而只有塌缩的外尔“暗辐射”的特殊情况下,可能会形成静态黑洞,其膜上具有纯5维引力势。
We investigate how braneworld gravity affects gravitational collapse and black hole formation by studying Oppenheimer-Snyder-like collapse on a Randall-Sundrum type brane. Without making any assumptions about the bulk, we show that the exterior spacetime on the brane is non-static. In the special case where there is no matter but only collapsing Weyl " dark radiation " , a static black hole may be formed, with purely 5-dimensional gravitational potential on the brane.
