Abstract

General relativity in double-pulsar PSR J0737-3039A/B with spin effects, was investigated. It was observed that greatest effect on orbital motion in double-pulsar system is the periastron precession, which amounts to 16° • 90 yr-1. The total angular momentum of whole system was found to remain constant such that precession of spins indicates a precession of total orbital angular momentum. The precession measurement of orbital angular momentum is a cleaner test as any such precession is a definite signature of spin effects.
