Braneworld Stars: Anisotropy Minimally Projected Onto the Brane
In the context of the Randall-Sundrum braneworld, an exhaustive and detailed
description of the approach based in the minimal anisotropic consequence onto
the brane, which has been successfully used to generate exact interior
solutions to Einstein's field equations for static and non-uniform braneworld
stars with local and non-local bulk terms, is carefully presented. It is shown
that this approach allows the generation of a braneworld version for any known
general relativistic solution.Comment: 15 pages, 1 figure. Schwarzschild's solution removed. References

Brane-world stars and (microscopic) black holes
We study stars in the brane-world by employing the principle of minimal
geometric deformation and find that brane-world black hole metrics with a tidal
charge are consistently recovered in a suitable limit. This procedure allows us
to determine the tidal charge as a function of the black hole ADM mass (and
brane tension). A minimum mass for semiclassical microscopic black holes can
then be derived, with a relevant impact for the description of black hole
events at the LHC.Comment: LaTeX, 11 pages, 2 figures. Final version to appear in PL
The Minimal Geometric Deformation Approach: a brief introduction
We review the basic elements of the Minimal Geometric Deformation approach in
details. This method has been successfully used to generate brane-world
configurations from general relativistic perfect fluid solutions.Comment: Brief review; minor corrections; references adde
