Descrição

A particular class of conformally flat spacetimes possessing isotropic and anisotropic pressure are investigated, using 1+3 formalism. We specialize the 1+3 equations obtained for the respective class of spacetimes to a compatible and simple equation of state where the energy per particle depends only on the particle density and the shear scalar.
