Abstract:
Binary pulsars represent a good laboratory for testing field theories in strong field regime. In such cases, the effects of non-linear terms in these theories would be easily measured. In the present work, we discuss an exact solution of Einstein’s field equations, in a field representing a binary compact object. The solution is a time-dependent one, which reduces to Curzon field, in the static case. The equations of motion of a test particle in the above mentioned field are formulated and solved. These equations can be used to study the motion of a third body (or a photon) in the field of a binary system.
