Abstract: Exact nonstatic spherically symmetric solutions of the Einstein equations for a null fluid source with pressure P and density \ensuremath{\rho} related by P=k${\mathrm{\ensuremath{\rho}}}^{\mathit{a}}$ are given. The a=1 metrics are asymptotically flat for 1/2k\ensuremath{\le}1 and cosmological for 0k1/2. 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-Nordstr\"om metrics. \textcopyright{} 1996 The American Physical Society.
