Massless field perturbations and gravitomagnetism in the Kerr-Taub-NUT spacetime
2003
Physical Review D, Particles and fields
A single master equation is given describing spin s<2 test fields that are gauge- and tetrad-invariant perturbations of the Kerr-Taub-NUT spacetime representing a source with mass M, gravitomagnetic monopole moment -ℓ and gravitomagnetic dipole moment (angular momentum) per unit mass a. This equation can be separated into its radial and angular parts. The behavior of the radial functions at infinity and near the horizon is studied and used to examine the influence of ℓ on the phenomenon of
