Effective perihelion advance and potentials in a conformastatic background with magnetic field
Abraão J. S. Capistrano, Antonio C. Gutiérrez-Piñeres
An Exact solution of the Einstein-Maxwell field equations for a conformastatic metric with magnetized sources is study. In this context, effective potential are studied in order to…
Anomalous precession of planets on a Weyl conformastatic solution
Abraão J. S. Capistrano, Joice A. M. Penagos, Manuel S. Alárcon
In this paper, we investigate the anomalous planets precession in the nearly-newtonian gravitational regime. This limit is obtained from the application of the slow motion conditio…
Test particles in a magnetized conformastatic spacetime
Antonio C. Gutiérrez-Piñeres, Abraão J. S. Capistrano, Hernando Quevedo
A class of exact conformastatic solutions of the Einstein-Maxwell field equations is presented in which the gravitational and electromagnetic potentials are completely determined b…
Implications on the cosmic coincidence by a dynamical extrinsic curvature
A. J. S Capistrano, L. A. Cabral
In this work, we apply the smooth deformation concept in order to obtain a modification of Friedmann equations. It is shown that the cosmic coincidence can be at least alleviated u…
