Most of the Petrov type D metrics obtained have the property that the velocity of the fluid does not lie in the two-space defined by the principal null directions of the Weyl tensor. The properties of the perfect-fluid sources are studied. Finally, a detailed analysis of a new class of spherically symmetric static perfect-fluid metrics is given.8 p.application/pdfeng(c) American Institute of Physics, 1988Física matemàticaPropietats de la matèriaFluidsMathematical physicsProperties of matterFluidsinfo:eu-repo/semantics/article60753info:eu-repo/semantics/openAccess
