Title: Confinement of exotic energy
Abstract: By solving the Einstein's field equations, we derive several configurations of compact objects with a nuclei of exotic energy in a static and spherically symmetric spacetime. In this talk I describe the derivation and several properties of the configurations, including the fact that in some of these objects can be reached a compacity as close to the black hole as desired, and the configurations remain without singularities or horizons. I present the evolution of some of the configuration which describe interesting dynamical spacetimes which seems to maintain the configuration at least for the time of the numerical evolution. I conclude mentioning some ideas which can be tested in these peculiar configurations.
