Abstract: (arXiv)
We observe critical phenomena in spherical collapse of radiation fluid. A sequence of spacetimes is numerically computed, containing models () that adiabatically disperse and models () that form a black hole. Near the critical point (), evolutions develop a self-similar region within which collapse is balanced by a strong, inward-moving rarefaction wave that holds constant as a function of a self-similar coordinate . The self-similar solution is known and we show near-critical evolutions asymptotically approaching it. A critical exponent is found for supercritical () models.References(9)
