Phys. Rev. D 76, 024003 (2007) [9 pages]Numerical simulations of gravitational collapse in Einstein-aether theoryReceived 20 March 2007; published 6 July 2007 We study gravitational collapse of a spherically symmetric scalar field in Einstein-aether theory (general relativity coupled to a dynamical unit timelike vector field). The initial value formulation is developed, and numerical simulations are performed. The collapse produces regular, stationary black holes, as long as the aether coupling constants are not too large. For larger couplings a finite area singularity occurs. These results are shown to be consistent with the stationary solutions found previously. © 2007 The American Physical Society URL:
