使用罗西X射线时变探测器的数据,得到了类星体PKS 1510-089从1996年1月到2009年12月在X射线的1.512 keV能段上的光变曲线.运用离散相关函数方法、小波分析方法和功率谱方法分析和认证类星体PKS 1510-089的光变周期值,结果表明类星体PKS 1510-089 在X射线的1.512 keV能段具有(0.940.08)a的平均光变周期.采用不同模型对观测到的周期性光变进行分析后的结果表明,超大质量双黑洞模型是目前解释类星体PKS 1510-089周期性光变较为理想的模型,应用

We present the X-ray light curve (1.512 keV) for quasar PKS 1510-089 with the observation of the all-sky monitor on the Rossi X-ray Timing Explorer from January 1996 to December 2009. Using the discrete correlation function method, the wavelet analysis method and the power spectrum method to analyze the data, we find that the light curve variability period of quasar PKS 1510-089 is (0.940.08)a. The super massive binary black hole model in used to analyze this source, and the results show that the orbit period of the super massive binary black hole system is (1.850.10)a and the super massive binary black hole model is the better model for describing the light curve periodic behaviour of quasar PKS 1510-089 at present.-
