Observation of critical phenomena and self-similarity in the gravitational collapse of radiation fluid | Charles R. Evans

23 Feb 1994 | Journal: | Phys.Rev.Lett. 72 (1994) 1782-1785 | Subject: | gr-qc | Abstract: | We observe critical phenomena in spherical collapse of radiation fluid. A sequence of spacetimes $cal{S}[eta]$ is numerically computed, containing models ($etall 1$) that adiabatically disperse and models ($etagg 1$) that form a black hole. Near the critical point ($eta_c$), evolutions develop a self-similar region within which collapse is balanced by a strong, inward-moving rarefaction wave that holds $m(r)/r$ constant as a function of a self-similar coordinate $xi$. The self-similar solution is known and we show near-critical evolutions asymptotically approaching it. A critical exponent $eta simeq 0.36$ is found for supercritical ($eta>eta_c$) models. | Source: | arXiv, gr-qc/9402041 | Services: | Forum | Review | PDF | Favorites |
