Parkes observations for project P789 semester 2019OCTS_05

Recently there has been great success at Parkes discovering millisecond pulsars (MSPs), a class that includes some of the most interesting and scientifically valuable pulsars known. In the last few years, we have discovered more than 40 MSPs though the High Time Resolution Universe Survey (P630) and Fermi searches (P675/P814). Here we propose to carry out precision timing of these sources to fully exploit these discoveries. Additionally, we continue to study the most significant of the discoveries from the Parkes Multibeam Pulsar Survey (P268). To maximise scientific impact, we have combined the most important sources from various previous proposals into this project, reducing total observation time required and easing the burden on the scheduler.

近年来，帕克斯天文台（Parkes）在毫秒脉冲星（millisecond pulsars, MSPs）的发现工作中取得了显著进展——该类天体包含了已知中部分最具科学价值与研究意义的脉冲星。过去数年间，我们依托高时间分辨率宇宙巡天（High Time Resolution Universe Survey, P630）以及费米（Fermi）搜寻项目（P675/P814），已发现超过40颗毫秒脉冲星。本次我们提议对这些天体开展高精度计时观测，以充分挖掘此次发现的科学潜力。此外，我们还将持续对帕克斯多波束脉冲星巡天（Parkes Multibeam Pulsar Survey, P268）中发现的最具科学价值的观测目标展开研究。为最大化科研产出与影响力，我们将此前多个提案中的核心观测目标整合至本项目中，以此压缩总观测所需时长，同时减轻观测调度的工作压力。
