Parkes observations for project P1165 semester 2022OCTS_07

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.

我们提议对500米口径球面射电望远镜（FAST）近期发现的五颗脉冲星候选体进行确认与测时。这些候选体是在对中等银纬区域开展的先导巡天中发现的，巡天采用六分钟指向观测模式。其中一颗候选体J1826-0049已被确认为脉冲星，其自转周期为4.59毫秒，处于一个轨道周期约6.3小时的双星系统中。FAST的超高灵敏度使其具备发现致密双星系统中脉冲星的潜力，因此我们提议利用帕克斯望远镜（Parkes）确认这些候选体的性质。我们还提议利用帕克斯望远镜对其中两颗最亮的候选体进行测时，以测量它们的自转与轨道参数。这些观测有望为利用新发现的脉冲星探索前沿物理开辟新的机遇。
