Abstract基于澳大利亚PARKES天文台射电数据和RXTE(Rossi X-ray Timing Explorer)中ASM(All Sky Monitor)的X射线数据对毫秒脉冲星J0437-4715进行两个波段的研究.对J0437-4715在射电波段的观测运用TEMPO2软件对不同终端系统的计时数据进行校准,提高了计时模型精度.用结构函数法,利用RXTE全天候扫描ASM的观测数据,对J0437-4715在X射线波段的光变进行中长期研究,发现它在X射线波段存在一个620 d的光变周期.
Other AbstractThe observations of the X-ray millisecond pulsar J0437-4715 in the radio and X-ray bands are analyzed and explored.In the radio band,the timing observations observed by different backend systems are calibrated with TEMP02,which improves the accuracy of timing model.Using the observation data of All Sky Monitor in Rossi X-ray Timing Explorer,the light curve of pulsar J0437-4715 in the X-ray band is generated with the structure function model.And a relative long-term period of(62030) days is found based on the 15-year data.
