论文摘要
明亮的无线电源S5 0716+714通常被归类为BL LAC对象，是最深入研究的Blazar之一。 S5 0716+714表现出极为奇特的特性，例如在Blazars中观察到的光学和极化变化的最短时间尺度。在给定的演讲中，我们介绍了S5 0716+714的8-H极化监视的结果，并使用SAO RAS的6-M望远镜BTA进行了$ \ sim70 $ -SEC分辨率。观察数据分析揭示了1.5小时时间尺度上指定未解决的发射区域大小的总和的变异性。建议使用磁场的螺旋结构的射流中极化的数值模型，并拟合该模型的磁场进液的周期约为15天。
The bright radio source S5 0716+714, which is usually classified as a BL Lac object, is one of the most intensively studied blazar. S5 0716+714 demonstrates extremely peculiar properties, such as the shortest time-scale of optical and polarimetric variations observed in blazars. In the given talk, we present the results of 8-h polarimetric monitoring of S5 0716+714 with a $\sim70$-sec resolution carried out using the 6-m telescope BTA of the SAO RAS. The observation data analysis reveals the variability both in total and polarized light on the 1.5-hour timescales that specifies the size of the unresolved emitting region. The numerical model of polarization in jet with the helical structure of the magnetic field is suggested, and fitting the model reveals a magnetic field precession with a period of about 15 days.
