Parkes observations for project P1165 semester 2022OCTS_01

We propose to confirm and time five pulsar candidates recently discovered by the Five-hundred-meter Aperture Spherical Telescope (FAST). These candidates were discovered during a pilot survey of an intermediate Galactic latitude region with six-minute pointings. One candidate, J1826-0049, has already been confirmed to be a 4.59 ms pulsar in a binary system with an orbital period of ~6.3 hr. The superior sensitivity of FAST has the potential to discover pulsars in compact binary systems and we propose to use Parkes to confirm the nature of these candidates. We also propose to time two of the brightest candidates with Parkes and measure their spin and orbital parameters. These observations have the potential to open new opportunities to probe exciting physics with these newly discovered pulsars.

本研究拟对五百米口径球面射电望远镜（Five-hundred-meter Aperture Spherical Telescope, FAST）新近发现的5颗脉冲星候选体开展证认与计时观测。这批候选体是在针对银道面中等纬度区域开展的6分钟指向试点巡天中被发现的。其中候选体J1826-0049已被证认为一颗轨道周期约6.3小时的双星系统内的4.59毫秒脉冲星。FAST卓越的探测灵敏度具备发现致密双星系统中脉冲星的潜力，本研究拟利用帕克斯（Parkes）望远镜对其余候选体的天体性质进行证认；同时，我们还计划使用帕克斯望远镜对其中两颗最亮的候选体进行计时观测，并测定其自转与轨道参数。上述观测工作有望为利用这批新发现的脉冲星开展前沿物理研究提供全新机遇。
