摘要

我们考虑Brans-Dicke标量张量理论，假设一个由低旋转运动和非零磁单极子的物质源产生的弱引力场。在这种情况下，我们确定了kerr - taub - nut型解和重力磁场。在此基础上，探讨了帧拖曳和引力磁时延对系统的影响，并与广义相对论的预测结果进行了比较。pac: 04.50。Kd, 04.25.Nx

Gravitomagnetic monopole in a scalar-tensor theory of gravity

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
