Kerr-Taub-NUT Spacetime with Maxwell and Dilaton Fields

Understand

We present an exact solution describing a stationary and axisymmetric object with electromagnetic and dilaton fields.

• The solution generalizes the usual Kerr-Taub-NUT (Newman-Unti-Tamburino) spacetime in general relativity and is obtained by boosting this spacetime in the fifth dimension and performing a Kaluza-Klein reduction to four dimensions.
• We also discuss the physical parameters of this solution and calculate its gyromagnetic ratio.
