Neutron star mass and spin implied by models of twinpeak quasiperiodic oscillations
Abstract
Binary pulsars represent a good laboratory for testing field theories in strong field regime. In such cases, the effects of nonlinear 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 timedependent 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.
