Abstract
A single master equation is given describing spin s 2 test field gauge
and tetrad-invariant perturbations of the Taub-NUT spacetime. This
solution of vacuum Einstein field equations describes a black hole with
mass M and gravitomagnetic monopole moment . This equation can be
separated into its radial and angular parts. The behaviour of the radial
functions at infinity and near the horizon is studied. The angular
equation, solved in terms of hypergeometric functions, can be related both
to spherical harmonics of suitable weight, resulting from the coupling of
the spin-weight of the field and the gravitomagnetic monopole moment of
the spacetime, and to the total angular momentum operator associated with
the spacetime's rotational symmetry. The results are compared with the
Teukolsky master equation for the Kerr spacetime.
