Abstract
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.
