Parkes observations for project P898 semester 2016OCTS

Our initial Parkes study of the 5.4-day eclipsing millisecond pulsar\r\n(MSP) J1417-4402 shows it to be the first system identified in the\r\nGalaxy on a standard evolutionary track that will end as a typical\r\nbinary MSP with a low-mass white dwarf companion. With the requested\r\ntiming observations we seek to characterize the late phase in the\r\nformation of a typical MSP binary, until now unobserved. In particular,\r\nwe aim to measure the pulsar spin-down luminosity, the orbital\r\neccentricity, and to search for gamma-ray pulsations.

我们针对5.4天食变毫秒脉冲星（millisecond pulsar, MSP）J1417-4402开展的初始帕克斯（Parkes）研究显示，该系统是银河系中首个被识别出的、处于标准演化轨道上的天体，其最终将演化为拥有低质量白矮星伴星的典型双星毫秒脉冲星。借助本次申请的计时观测，我们旨在表征典型双星毫秒脉冲星形成过程中的晚期阶段——这一阶段迄今为止尚未被观测到。具体而言，我们计划测量该脉冲星的自旋减速光度、轨道偏心率，并搜寻γ射线脉冲。
