Confinement of exotic energy

By solving the Einstein's field equations, we derive several
configurations of compact objects with a nucleus 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 by mentioning some ideas which can be tested in
these peculiar configurations.
