Trapped surfaces in Oppenheimer-Snyder black holes
2013 (English)In: Physical Review D, ISSN 1550-7998, Vol. 88, 064012- p.Article in journal (Refereed) Published
The Oppenheimer-Snyder solution models a homogeneous round dust of cloud collapsing to a black hole. Inside its event horizon there is a region through which trapped surfaces pass. We try to determine exactly where the boundary of this region meets the center of the cloud. We present explicit examples of the relevant trapped (topological) spheres; they extend into the exterior vacuum region, and are carefully matched at the junction between the cloud and the vacuum.
