Gravitational Collapse on the Brane

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.
