Non-static, spherically symmetric, shear-free, perfect-fluid solutions of Einstein's equations
Il Nuovo Cimento B, 2004The Einstein equations for non-static, shear-free, spherically symmetric, perfect-fluid distributions reduce to one second-order non-linear differential equation in the radial parameter. General solutions of this equationhave been obtained in Class. Quantum Grav., 16 (1999) 3553 by symmetry analysis.

Exact solutions to Einstein's field equations for perfect spherically symmetric static fluids
Classical and Quantum Gravity, 2009We show that Einstein's field equations have two metric solutions for any given mass density of a perfect spherically symmetric static fluid. We illustrate this general result for specific cases in which the metric and mass are both in closed form. Hence solutions can be grouped by mass function, as an association of distinct metrics that differs from ...

The Jordan-Brans-Dicke field equations [1] contain the four-dimensional field equations of the five-dimensional projective unified theory. As it should be, Einstein's theory is incorporated as a limiting case. In this paper we present a method to determine explicitly for every static spherically symmetric solution of Einstein's theory with perfect ...
