Jurkevich方法在3C120天体光变周期分析中的应用

Computing the Period of Light Variability in Seyfert Galaxy 3c120 Using the Jurkevich Method

文章收集了3C120天体光学B波段较为完备的观测数据,并获得了其长期光变曲线。利用Jurkevich方法对其中B波段的数据进行了分析,通过研究发现其中存在有318d的光变周期。该方法对寻找3C120天体的光变周期有很大帮助,也能为其他周期计算服务。

This text has collected all available optical B magnitudes of seyfert galaxy 3c120 more than 6 years and acquires its long - term light curve. We make an analysis to its B band data with the Jurkevich method. We have found that it exists an approximate period of 318d. This method is useful in finding period of seyfert galaxy 3c120, and it is also extensively adopted during cyclic analysis in other domains.
