Abstract

The aim of this work is to apply a tensor-theory to a problem with spherical symetry. First, we make a reminder about the basic concepts of general relativity and a short introduction about tensor-scalar theories. Particulary, we present the Abnormally Weighting Energy hypothesis and the equilibrium equations resulting. These equations compose a boundary value problem. In the continuation of this work, we show the results of the integration of the system. First, we analyze the equilibrium conditions of a body composed with only one fluid with constant density and spontaneous scalarization. The last results are about a body containing two fluids with dominance of one of them at the center. These last results are original.
