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 motion 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. PACS: 04.50.Kd, 04.25.Nx
