Spherical symmetry in a dark energy permeated space-time
  The properties of a spherically symmetric static space-time permeated of dark
energy are worked out. Dark energy is viewed as the strain energy of an
elastically deformable four dimensional manifold. The metric is worked out in
the vacuum region around a central spherical mass/defect in the linear
approximation. We discuss analogies and differences with the analogue in the de
Sitter space time and how these competing scenarios could be differentiated on
an observational ground. The comparison with the tests at the solar system
scale puts upper limits to the parameters of the theory, consistent with the
values obtained applying the classical cosmological tests.
