Abstract:
Possible astrophysical consequences of the Hořava quantum gravity theory
have been recently studied by several authors. They usually employ the
Kehagias-Sfetsos (KS) spacetime which is a spherically symmetric vacuum
solution of a specific version of Hořava’s gravity. The KS metric has
several unusual geometrical properties that in the present article we
examine by means of the often used technique of embedding diagrams. We
pay particular attention to the transition between naked singularity and
black-hole states, which is possible along some particular sequences of
the KS metrics.
