The Hanle and Zeeman Effects in Solar Spicules

R. Ramelli, M. Bianda, L. Merenda, J. Trujillo Bueno

摘要:

在洛迦诺的格雷戈里-库德望远镜上,用ZIMPOL偏振计记录了大量的针状体中He-D3线的高精度全斯托克斯偏振光谱观测。观测技术使我们能够获得测量自由看到诱导的虚假效应。仪器极化得到了很好的控制,并在数据分析中得到了考虑。根据Hanle和Zeeman效应的量子理论解释所观察到的Stokes分布,目的是获得关于磁场矢量的信息。为此,我们利用一个合适的斯托克斯反演技术。结果给出了几个特别有趣的测量,清楚地显示了操作的汉勒和塞曼效应在太阳色球针状物的重点。

英文摘要:

A large set of high precision full-Stokes spectropolarimetric observations of the He-D3 line in spicules has been recorded with the ZIMPOL polarimeter at the Gregory-Coude Telescope in Locarno. The observational technique allow us to obtain measurements free from seeing induced spurious effects. The instrumental polarization is well under control and taken into account in the data analysis. The observed Stokes profiles are interpreted according to the quantum theory of the Hanle and Zeeman effects with the aim of obtaining information on the magnetic field vector. To this end, we make use of a suitable Stokes inversion technique. The results are presented giving emphasis on a few particularly interesting measurements which show clearly the operation of the Hanle and Zeeman effects in solar chromospheric spicules.
