Zipoy-Voorhees Gravitational Object as a Source of High-Energy Relativistic Particles
Original language description
The Zipoy-Voorhees solution is known as the gamma-metric and/or q-metric being static and axisymmetric vacuum solution of Einstein field equations which becomes strong curvature naked singularity. The metric is characterized by two parameters, namely, the mass M and the dimensionless deformation parameter gamma. It is shown that the velocity of test particle orbiting around the central gamma-object can reach the speed of light, consequently, the total energy of the particle will be very high for a specific value the deformation parameter of the spacetime. It is also shown that causality problem arises in the interior region of the physical singularity for the specific value of the deformation parameter when test particles can move with superluminal velocity being greater than the speed of light that might be an additional tool for explaining the existence of tachyons for gamma>1/2 which are invisible for an observer.
