The Periodicity Analysis of the Radio Flux Variability about PKS 1510-089 with Period04 Method
Abstract
We have collected the 37 GHz radio data of PKS 1510-089 from 1990 to 2005. After dealing with these data, we obtain its long-term light curve. From the light curve, we can see that PKS 1510-089 is very active. In this paper, we firstly make use of Period04 method to analyze the period of light variation about PKS 1510-089. The results show that PKS 1510-089 has the periods (1.87±0.13) yr and (0.87±0.07) yr at 37 GHz, which is consistent with the results of other authors who use different methods from ours (Xie et al. & Wu et al.).
