Title |
Exact galactic disk-haloes model in Einstein-Maxwell gravity | |||||
| Coauthors | ||||||||
|
Abstract |
An exact model in Einstein-Maxwell gravity describing a magnetized galactic disk-halo system is presented. The description of properties of the stationary metric and its source is discussed. All the expressions are presented in terms of an Harmonic function. A ``generalization'' of the Kuzmin potential is used as a particular example. The solution obtained is asymptotically Minkowskian in general and turns out to be free of singularities. All the relevant quantities show a reasonable physical behaviour. |

Title |
Motion of test particles in a magnetized conformastatic background | |||||
| Coauthors | A. J. S. Capistrano | |||||||
|
Abstract |
A class of Exact conformastatic solutions of the Einstein-Maxwell field equations is presented in which the gravitational and electromagnetic potentials are completely deter- mined by a harmonic function only. The motion of uncharged and charged particles is investigated in the background of a space-time characterized by this class of solutions. We focus on the study of circular stable and unstable orbits obtained by taking account particulars harmonic functions defining the gravitational potential. The study of perihelion advance of the test particles is also considered. |
