Conformastationary disk-haloes in Einstein–Maxwell gravity
(Springer New York LLC, 2015)
An exact solution of the Einstein–Maxwell field equations for a conformastationary metric with magnetized disk-haloes sources is worked out in full. The characterization of the nature of the energy momentum tensor of the ...
C 3 matching for asymptotically flat spacetimes
(Institute of Physics Publishing, 2019)
We propose a criterion for finding the minimum distance at which an interior solution of Einstein's equations can be matched with an exterior asymptotically flat solution. The location of the matching hypersurface is thus ...
Conformastatic disk-haloes in Einstein-Maxwell gravity
(2013)
We present a relativistic model describing a thin disk surrounded by a halo in the presence of an electromagnetic field. The model is obtained by solving the Einstein-Maxwell equations on a particular conformastatic spacetime ...
Electromagnetic sources distributed on shells in a Schwarzschild background
(2011)
In the Introduction we briefly recall our previous results on stationary electromagnetic fields on black hole backgrounds and the use of spin-weighted spherical harmonics. We then discuss static electric and magnetic test ...
Exact relativistic models of thin disks around static black holes in a magnetic field
(2014)
The exact superposition of a central static black hole with surrounding thin disk in presence of a magnetic field is investigated. We consider two models of disk, one of infinite extension based on a Kuzmin-Chazy-Curzon ...
Variational thermodynamics of relativistic thin disks
(Springer New York LLC, 2015)
We present a relativistic model describing a thin disk system composed of two fluids. The system is surrounded by a halo in the presence of a non-trivial electromagnetic field. We show that the model is compatible with the ...
Monopole and dipole layers in curved spacetimes: Formalism and examples
(2011)
The discontinuities of electromagnetic test fields generated by general layers of electric and magnetic monopoles and dipoles are investigated in general curved spacetimes. The equivalence of electric currents and magnetic ...
Stationary axially symmetric relativistic thin discs with nonzero radial pressure
(2012)
A detailed analysis of the surface energymomentum (SEMT) tensor of stationary axially symmetric relativistic thin discs with nonzero radial pressure is presented. The physical content of the SEMT is analysed and expressions ...
An Infinite Family of Magnetized Morgan-Morgan Relativistic Thin Disks
(2012)
Applying the Horský-Mitskievitch conjecture to the empty space solutions of Morgan and Morgan due to the gravitational field of a finite disk, we have obtained the corresponding solutions of the Einstein-Maxwell equations. ...
Exact galactic disk-haloes model in Einstein-Maxwell gravity
(World Scientific Publishing Co. Pte. Ltd., 2018)
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 are discussed. All the expressions are presented ...
