Measurement of Orbital Decay in the Double Neutron Star Binary PSR B2127+11C
We report the direct measurement of orbital period decay in the double neutron star pulsar system PSR B2127+11C in the globular cluster M15 at the rate of (-3.95 ± 0.13) × 10^-12, consistent with the prediction of general relativity at the ∼ 3 = (1.358 ± 0.010) M_ and the companion mass m_c = (1.354 ± 0.010) M_. We also report long-term pulse timing results for the pulsars PSR B2127+11A and PSR B2127+11B, including confirmation of the cluster proper motion.doi:10.1086/505742 fatcat:su47mav75vd4padkkmlhgkgvve
