Magnetized Taub-NUT spacetime
arXiv:2101.06510 · doi:10.1016/j.nuclphysb.2022.115741
Abstract
We find an exact solution describing the spacetime outside a massive object with NUT parameter embedded in an external magnetic field. To get the solution, we employ the Ernst magnetization transformation to the Taub-NUT metric as the seed solution. The massless limit of this new solution is the Melvin-Taub-NUT spacetime. Some aspects in the magnetized Taub-NUT spacetime are investigated, such as the surface geometry, the existence of closed time like curve, and the electromagnetic properties.
