Circular geodesics of naked singularities in the Kehagias-Sfetsos metric of Hořava's gravity

Ronaldo S. S. Vieira, Jan Schee, Włodek Kluźniak +2

We discuss photon and test-particle orbits in the Kehagias-Sfetsos (KS) metric. For any value of the Hořava parameter $\omega$, there are values of the gravitational mass $M$ for which…
