Gravitomagnetic effects of a massive and slowly rotating sphere with an equatorial mass current on orbiting test particles

Abstract

Within the framework of linearized Einstein field equations we compute the gravito-magnetic effects on a test particle orbiting a slowly rotating, spherical body with a rotating matter ring fixed to the equatorial plane. Our results show that the effect on the precession of particle orbits is increased by the presence of the ring.
