Motion of test particles in the field of a naked singularity
(American Physical Society, 2016)
We investigate the motion of test particles in the gravitational field of a static naked singularity generated by a mass distribution with a quadrupole moment. We use the quadrupole metric (q metric) which is the simplest ...
Test particles in a magnetized conformastatic spacetime
(American Physical Society, 2016)
A class of exact conformastatic solutions of the Einstein-Maxwell field equations is presented in which the gravitational and electromagnetic potentials are completely determined by a harmonic function. We derive the ...
Newman–Janis Ansatz in conformastatic spacetimes
(Springer New York LLC, 2016)
The Newman–Janis Ansatz was used first to obtain the stationary Kerr metric from the static Schwarzschild metric. Many works have been devoted to investigate the physical significance of this Ansatz, but no definite answer ...
On classical thermal stability of black holes with a dynamical extrinsic curvature
(Academic Press Inc., 2017)
We study the deformation caused by the influence of the extrinsic curvature on a vacuum spherically symmetric metric embedded in a five-dimensional bulk. We investigate the resulting black-holes obtaining general characteristics ...
Motion of test particles in a magnetized conformastatic background
(World Scientific Publishing Co. Pte. Ltd., 2018)
A class of exact conformastatic solutions of the Einstein-Maxwell field equations is presented in which the gravitational and electromagnetic potentials are completely determined by a harmonic function only. The motion of ...
An infinite family of relativistic magnetized finite thin disks
(Institute of Physics Publishing, 2011)
An infinite family of relativistic finite thin disk model with magnetic field is presented. The model is obtained for solving the Einstein-Maxwell equations for static spacetimes by means of the Horsk-Mitskievitch generating ...
A static axisymmetric exact solution of f(R)-gravity
(2013)
We present an exact, axially symmetric, static, vacuum solution for f(R)-gravity in Weyl's canonical coordinates. We obtain a general explicit expression for the dependence of df(R)/dR upon the r and z coordinates and then ...
