  • 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-hr orbit. We have continued its observations with the Arecibo radio telescope and have now measured the individual neutron star masses of this system. We find the pulsar and companion masses to be 1.295± 0.011 M and 1.310± 0.011 M (2σ − 95% confidence, unless stated otherwise), respectively. We have also measured the proper motion… CONTINUE READING
