| 英文摘要 | The light curve data from 1894 to 2008 are compiled for the BL Lacertae object OJ 287 from the available literature. Periodicity analysis methods (the Discrete Correlation Function-DCF, the Jurkevich method, the power spectral (Fourier) analysis, and the CLEANest method) are performed to search for possible periodicites in the light curve of OJ 287. Significance levels are given for the possible periods. The analysis results confirm the existence of the 12.2 +/- 0.6 yr time scale and show a hint of a similar to 53 yr time scale. The 12.2 +/- 0.6 yr period is used as the orbital period to investigate the supermassive binary black hole system parameters. |
