Shearfree Spherically Symmetric Fluid Models [PDF]
M. Sharif, Z. YousafWe try to find some exact analytical models of spherically symmetric spacetime of collapsing fluid under shearfree condition. We consider two types of solutions: one is to impose a condition on the mass function while the other is to restrict the pressure. We obtain totally of five exact models, and some of them satisfy the Darmois conditions.View original: http://arxiv.org/abs/1306.1024
