Corotating binary systems of identical Kerr-Newman black holes
Cabrera Munguia, Roberto Ivan (2020-11-05)In the present paper binary configurations of identical corotating Kerr-Newman black holes separated by a massless strut are derived and studied. After solving the axis conditions and establishing the absence of magnetic ... -
The relations between the multipole moments in axistationary electrovacuum spacetimes and the N-soliton solution
Cabrera Munguia, Roberto Ivan; Costa Filho, Etevaldo dos Santos; Costa Filho, Etevaldo dos Santos; guimarães, Angelo (2022-01-27)A general formulation of the relativistic multipole moments in axistationary electrovac spacetimes is introduced in a closed analytical form. We give a complete description of how the Ernst potentials on the symmetry axis ...
