摘要
从文献资料中收集了AO0235+164天体光学B波段和射电4.8GHz、37GHz十几年的观测有效数据,并获得了其长期的光变曲线,从光变曲线可以看出其活动是非常剧烈的。利用了Jurkevich方法和自相关函数方法分别对AO 0235+164进行了周期性分析,研究结果表明,其可能存在大约3.14±0.16a的光变周期。而Raiteri等人发现5-6a的光变周期可能是3.14±0.16a光变周期的叠合。
From many literatures,we have collected about vicennial datapoints of effective observation of BL Lac AO 0235+164 in the optical B band and in the radio bands with 4.8GHz and 37GHz,and constructed its long-term light curve.The light curve shows that AO 0235+164 is very active.We used Jurkevich method and DCF autocorrelation function to analyze the periods of the optical B band and radical band with 4.8GHz and 37 GHz.Our results show that the long-term period of variation is about 3.14±0.16 years.Time of coincidence is possible.Raiteri et al.have found the period of 5~6 year,which may be a double of 3.14±0.16 years periods.
