TITLE Static black holes with back reaction from vacuum energy
ABSTRACT

We study spherically symmetric static solutions to the semi-classical Einstein equation
sourced by the vacuum energy of quantum fields in the curved space-time of the same solution.
We found solutions that are small deformations of
the Schwarzschild metric for distant observers, but without horizon.
Instead of being a robust feature of objects with high densities,
the horizon is sensitive to the energy-momentum tensor in the near-horizon region.
