Fe I 1564.8 nm中的网络磁场

Internetwork Magnetic Fields Seen in Fe I 1564.8 nm

Yoichiro Hanaoka, Takashi Sakurai

摘要:

利用2010- 2019年期间获得的\ion{Fe}{1} 1564.8 nm谱线的全圆盘斯托克斯$V/I$图,我们研究了太阳光球中互联网络磁场的性质。与以前的大多数研究相比,我们使用的数据具有中等的空间和光谱分辨率。尽管如此,我们能够区分网络间的字段组件和有源区/网络边界组件使用大塞曼分裂的\ion{Fe}{1} 1564.8 nm线。因此,我们的分析提供了一个与以往研究截然不同的观点。我们统计分析的数据没有普通的反演,但我们成功地得出了一些性质的互联网络领域,互联网络充满了小规模的磁场,其强度是在弱场范围内的\ion{Fe}{1} 1564.8 nm线(300- 400 G或更少),和互联网络领域是高度倾斜。虽然这些结果是从不同的角度进行分析获得的,但它们与以前的大多数发现是一致的。此外,在第24太阳活动周的大部分时间里,没有发现网间场的显著变化。

英文摘要:

We studied the properties of internetwork magnetic fields in the solar photosphere taking advantage of full-disk Stokes $V/I$ maps of the \ion{Fe}{1} 1564.8 nm line, which were obtained during 2010--2019. In contrast to most of the previous studies, we used data with moderate spatial and spectral resolutions. Nonetheless, we were able to distinguish the internetwork field components and the active region / network boundary components using large Zeeman splitting of the \ion{Fe}{1} 1564.8 nm line. Thus, our analysis provides a point of view quite different from that of the previous studies. We analyzed the data statistically without ordinary inversions, yet we successfully derived some properties of internetwork fields; the internetwork is filled with small-scale magnetic fields, their strength is within the weak-field regime of the \ion{Fe}{1} 1564.8 nm line (300--400 G or less), and the internetwork fields are highly inclined. Although the results were obtained from the analysis performed from a different perspective, they are consistent with the majority of the previous findings. In addition, no notable variation in the properties of the internetwork fields was found during the period covering most of solar cycle 24.
