英文摘要We report the timing analysis of PSR J1846-0513, a pulsar discovered by the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in Commensal Radio Astronomy FAST Survey. The pulsar possesses a spin period of 23.36 ms and a spin-down rate ( P ) of 1.0106(3) x 10-18 s s-1, and it is located in an eccentric orbit (e similar to 0.208) with an orbital period of 0.61 days. The characteristic age and surface magnetic field of the pulsar are found to be 366.62 Myr and 4.9178 x 109 G, respectively, indicating that it is a recycled pulsar. Using over two years of timing data, we measure the periastron advance omega = 0.8956(8) deg yr-1. By assuming that this effect is purely relativistic, we have estimated the total mass M = 2.6287(35)M circle dot and obtained an upper limit for the pulsar mass and a lower limit for the companion's mass. Our results indicate that this is a double neutron star system.
