The NUT metric is interpreted as the field of ( a ) a mass around the origin of coordinates, and ( b ) a semi-infinite massless source of angular momentum. 
An Einstein — NUT metric
A metric satisfyingEinstein’s equations is given which in the vicinity of the source reduces to the well-known NUT metric and which in the absence of the source reduces to the metric ofEinstein’s
GEOMETRICAL INTERPRETATION OF THE NUT METRIC
TLDR
This paper presents a five-dimensional representation of the reduced metric and concludes that the seed metric should be considered as a discrete-time metric.
Constraints on magnetic mass
The authors show that in any spacetime with magnetic mass, there is necessarily a quantisation of energy arising from the fact that wavefunctions must be single valued. This in turn is equivalent to
A class of stationary solutions of the Einstein-Maxwell equations
The class depends on one harmonic function and two additional arbitrary constants. It refers to sources with spin and electric or magnetic charge, and includes some space-times which are flat at
A class of stationary axisymmetric solutions of Einstein-Maxwell scalar field theories
A class of exact stationary axisymmetric multi-wormhole solutions of the Einstein-Maxwell scalar field equations, depending on a single real potential, is generated from the corresponding static
Rotating perfect fluid sources of the NUT metric
Locally rotationally symmetric perfect fluid solutions of Einstein's gravitational equations are matched along the hypersurface of vanishing pressure with the NUT metric. These rigidly rotating
Symmetries and Motions in NUT-Taub Spinning Space
Abstract We review the geodesic motion of pseudo-classical spinning particles in curved space. We describe the generalized Killing equations for spinning spaces and express the constants of motion.
The first law of black hole thermodynamics for Taub-NUT spacetime
This article focuses on the new approach to the nature of a nut parameter $n$, usually treated as a dual charge to the mass. Instead of thinking about it as a gravitational analog of the magnetic
Kerr-Taub-NUT Spacetime with Maxwell and Dilaton Fields
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)
NUT-like and near-horizon limits of Kerr-NUT-(A)dS spacetimes
We study a class of limits of the higher-dimensional Kerr-NUT-(A)dS spacetimes where particular roots of metric functions degenerate. Namely, we obtain the Taub-NUT-(A)dS and the extreme near-horizon

Empty-Space Generalization of the Schwarzschild Metric
A new class of empty‐space metrics is obtained, one member of this class being a natural generalization of the Schwarzschild metric. This latter metric contains one arbitrary parameter in addition to

The invariant character of restrictions imposed on singularities or other sources of the gravitational fields in the Einstein-Infeld-Hoffmann theory of motion in general relativity is examined. A
