We report here the Einstein@Home discovery of PSR J1913+1102, a 27.3 ms pulsar found in data from the ongoing Arecibo PALFA pulsar survey. The pulsar is in a 4.95 hr double neutron star (DNS) system with an eccentricity of 0.089. From radio timing with the Arecibo 305 m telescope, we measure the rate of advance of periastron to be $\dot{\omega }=5.632(18)$° yr−1. Assuming general relativity accurately models the orbital motion, this corresponds to a total system mass of M tot = 2.875(14) ${M}_… 35 Citations ## Figures and Tables from this paper PALFA Discovery of a Highly Relativistic Double Neutron Star Binary • Physics • 2018 We report the discovery and initial follow-up of a double neutron star (DNS) system, PSR J1946$+$2052, with the Arecibo L-Band Feed Array pulsar (PALFA) survey.

This work reports the discovery of a 22-ms pulsar, PSR J0737–3039, which is a member of a highly relativistic double-neutron-star binary with an orbital period of 2.4 hours, which implies an order-of-magnitude increase in the predicted merger rate for double- NEUTron- star systems in the authors' Galaxy (and in the rest of the Universe).
