Exact non-spherical relativistic star
  We obtain Vaidya-like solutions to include both a null fluid and a string fluid in non-spherical (plane symmetric and cylindrical symmetric) anti-de Sitter space-times. Assuming that string fluid diffuse, we find exact solutions of Einstein's field equations. Thus we extend a recent work of Glass and Krisch \cite {gk} to non-spherical anti-de Sitter space-times.
