Particle Motion and Acceleration Around Black Holes in Horava-Lifshitz Gravity

Analytical solutions of Maxwell equations in background spacetime of black hole in Hořava-Lifshitzgravity immersed in external uniform magnetic field have been found. Influence of magnetic and parameters of Hořava-Lifshitzgravity on equation of motion of charged test particle around black hole in Hořava-Lifshitzgravity in magnetic field has been investigated. Exact analytical solution for dependence of the radius of the innermost stable circular orbits (ISCO) from parameters of Hořava-Lifshitzgravity for motion of test particle around isolated black hole in Hořava-Lifshitzgravity has been derived. The Penrose process on rotational energy extraction of the black hole in the original non-projectable Hořava-Lifshitz gravity is studied. The strong dependence of the extracted energy from the special range of parameters of the Hořava-Lifshitz gravity has been found. Particle acceleration near the rotating black hole in Hořava-Lifshitz gravity has been studied. It is shown that the fundamental parameter of the Hořava-Lifshitz gravity can impose a limitation on the energy of the accelerating particles preventing them from the infinite value.
