Abstract (from CDS):

PSR J1829+2456 is a radio pulsar in a relativistic binary system with another neutron star. It has a rotational period of 41 ms and a mildly eccentric (e = 0.14) 28 h orbit. We have continued its observations with the Arecibo radio telescope and have now measured the individual neutron star masses of this system: The pulsar and companion masses are 1.306 ±0.007 M☉ and 1.299 ±0.007 M☉ (2σ - 95 per cent confidence, unless stated otherwise), respectively. We have also measured the proper motion for this system and used it to estimate a space velocity of 49+77–30 km s–1 with respect to the local standard of rest. The relatively low values for companion mass, space velocity, and orbital eccentricity in this system make it similar to other double neutron star systems in which the second-formed neutron star is thought to have formed in a low-kick, low mass-loss, symmetric supernova.
