The orbital effect of photon in the general stationary spacetime

Abstract

We calculate the orbital effect of photon in the axisymmetric field created by the spinning mass with electric charge and a large number of magnetic monopoles. By analyzing the result we found that the deflection effect caused by the electric charge and magnetic charge decreases the deflection effect caused by the mass of the field source, but the deflection effect caused by the spinning of the field source depends on the angle between the spinning direction of the field source mass and the direction of photon motion. We obtained interesting results in discussing the parameters of the celestial body.
