Phys. Rev. D 75, 064007 (2007) [15 pages]Outer trapped surfaces in Vaidya spacetimesReceived 29 November 2006; published 8 March 2007 It is proven that in Vaidya spacetimes of bounded total mass, the outer boundary, in spacetime, of the region containing outer trapped surfaces, is the event horizon. Further, it is shown that the region containing trapped surfaces in these spacetimes does not always extend to the event horizon. © 2007 The American Physical Society URL:
