摘要:

我们提出了一个更新的时间解决方案和分析的配置文件的演变-包括岁差和光束形状-的年轻,相对论性的脉冲星J1906+0746。这颗144毫秒的脉冲星在3.98小时轨道上,偏心率为0.085(Lorimer等人,2006年),最初是在使用305米阿雷西博望远镜进行的ALFA(阿雷西博L波段馈源阵列)脉冲星巡天(Cordes等人,2006年)的早期阶段发现的,随后在帕克斯多波束巡天数据档案中发现。从那以后,我们一直使用阿雷西博和格林班克望远镜定期监测该系统,并包括来自Jodrell Bank,Parkes,Nancay和Westerbork望远镜的数据。双星伴星的性质也将根据从更新的时间解获得的总质量和伴星质量的改进估计进行讨论。

英文摘要:

We present an updated timing solution and an analysis of the profile evolution - including precession and beam shape - of the young, relativistic binary pulsar J1906+0746. The 144-ms pulsar, in a 3.98-hour orbit with eccentricity 0.085 (Lorimer et al. 2006), was initially discovered during the early stages of the ALFA (Arecibo L-band Feed Array) pulsar survey (Cordes et al. 2006) using the 305-metre Arecibo telescope and was subsequently found in archival Parkes Multibeam Survey data. We have since been regularly monitoring the system using the Arecibo and Green Bank telescopes, and include data from the Jodrell Bank, Parkes, Nancay and Westerbork telescopes. The nature of the binary companion will also be discussed based on improved estimates of the total and companion masses obtained from the updated timing solution.
