    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.
