The Radiant Massive Magnetic Dipole (2310.15979v1)
Published 24 Oct 2023 in gr-qc, math-ph, and math.MP
Abstract: We present an exact, time-dependent solution for the Einstein field equations that models the coupling between an anisotropic fluid and a magnetic field in an axially symmetric space-time. By carefully selecting the metric components, we achieve a convenient separation of variables that enables us to solve Einstein's field equations and obtain a solution that evolves into the Gutsunaev-Manko massive magnetic dipole. The analysis of the thermodynamic quantities suggests that this solution may represent a pulse of radiation emitted by a massive object with magnetic properties as for example pulsars or neutron stars.
