BL Lac天体AO0235+164的长期光变周期分析

The Long-term Variability Periodicity Analysis for the BL Lacertae Object AO 0235+164

通过有关文献收集了天体AO0235+164的光学B波段的资料,用Jurkevich方法讨论了其周期性,并采用几种方法(离散相关函数(DCF)法,MontelCarlo法,折叠法等)对所得结果进行了分析.结果表明,该天体可能存在一个时标为1.56a的周期.

The optical measurements of AO 0235 + 164 are compiled for the searching of periodicity in the light curve using the Jurkevich method. The false periods are ruled out using the Montel Carlo method, a possible period of 1. 56 year is shown.
