Gravitomagnetic monopole in a scalar-tensor theory of gravity.

Abstract

We consider the Brans-Dicke scalar-tensor theory, supposing a weak gravitational field generated by a material source with low rotating mo- tion and nonzero magnetic monopole. In this context, we determine a Kerr-Taub-NUT-type solution and the gravitomagnetic field. After, the effects of frame dragging and gravitomagnetic time delay are explored and the results obtained are compared with those predicted by General Relativity.
