Parkes observations for project P1330 semester 2024OCTS_04

We discovered PSR J1716-2808A (NGC6316A), a highly accelerated binary millisecond pulsar (MSP), in NGC6316. We are currently observing it with Parkes (P1330) to solve for the orbit. At the time of this proposal submission, we have not yet solved the orbit. We have 6 scheduled observations in August 2024, which we expect to provide a good orbital solution to use in the proposed observations for this proposal. The goal of the proposed observations is to conduct a year long timing campaign. This is crucial to break the timing degeneracy that occurs between the pulsar's position and the pulsar's spindown rate. We will be able to use this to connect the pulsar to our previous observations spanning back to 2022. This will also confirm whether the pulsar is a part of the cluster. A secondary advantage of having these observations is that the data can also be used to search for faint pulsars via stack searching and time any new pulsars that are discovered in any subsequent observations.我们在NGC6316星团中发现了PSR J1716-2808A（又名NGC6316A），这是一颗具有高轨道加速度的双星毫秒脉冲星（millisecond pulsar, MSP）。目前我们正使用帕克望远镜（Parkes，编号P1330）对其开展观测以求解轨道参数。本提案提交之时，我们尚未完成轨道参数的求解工作。我们已安排2024年8月的6次观测任务，预期这些观测将能获得可靠的轨道解，用于本提案中规划的后续观测。本次提案规划的观测目标是开展为期一年的计时观测项目，这对于破解脉冲星位置与自转减速率之间存在的计时简并问题至关重要。借此我们可将该脉冲星与我们2022年以来的既往观测数据进行关联，同时还可验证该脉冲星是否隶属于NGC6316星团。本次观测的另一项附加优势在于，所得数据还可通过叠合搜索法搜寻暗弱脉冲星，并为后续观测中发现的新脉冲星提供计时观测支持。
