Abstract

Exact non-static spherically symmetric solutions of the Einstein equations for a null fluid source with pressure P and density ρ related by P = kρ^a are given. The a=1 metrics are asymptotically flat for 1/2<k≤ 1 and cosmological for 0<k<1/2. The k=1 metric is the known charged Vaidya solution. In general the metrics have multiple apparent horizons. In the long time limit, the asymptotically flat metrics are hairy black hole solutions that `fall between' the Schwarzschild and Reissner-Nordstrom metrics.
