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 ...
Two-dimensional Einstein manifolds in geometrothermodynamics
(2013)
We present a class of thermodynamic systems with constant thermodynamic curvature which, within the context of geometric approaches of thermodynamics, can be interpreted as constant thermodynamic interaction among their ...
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 ...
Exact relativistic magnetized haloes around rotating disks
(Hindawi Publishing Corporation, 2015)
The study of the dynamics of magnetic fields in galaxies is one of important problems in formation and evolution of galaxies. In this paper, we present the exact relativistic treatment of a rotating disk surrounded by a ...
Effective Perihelion Advance and Potentials in a Conformastatic Background with Magnetic Field
(Hindawi Limited, 2016)
Exact solutions of the Einstein-Maxwell field equations for a conformastatic metric with magnetized sources are investigated. In this context, effective potentials are studied in order to understand the dynamics of the ...
