We study the motion of test particles and electromagnetic waves in the KerrNewmanTaubNUT spacetime in order to elucidate some of the effects associated with the gravitomagnetic monopole moment of the source. In particular, we determine in the linear approximation the contribution of this monopole to the gravitational time delay and the rotation of the plane of the polarization of electromagnetic waves. Moreover, we consider 'spherical' orbits of uncharged test particles in the KerrTaubNUT spacetime and discuss the modification of the Wilkins orbits due to the presence of the gravitomagnetic monopole

Abstract
We study the motion of test particles and electromagnetic waves in the KerrNewmanTaubNUT spacetime in order to elucidate some of the effects associated with the gravitomagnetic monopole moment of the source. In particular, we determine in the linear approximation the contribution of this monopole to the gravitational time delay and the rotation of the plane of the polarization of electromagnetic waves. Moreover, we consider 'spherical' orbits of uncharged test particles in the KerrTaubNUT spacetime and discuss the modification of the Wilkins orbits due to the presence of the gravitomagnetic monopoleFile in questo prodotto:
