Anomalous circular polarization profiles in the He I 1083.0 nm multiplet from solar spicules
摘要：
我们报告斯托克斯矢量观测太阳针状体和日珥在他我1083 nm多重峰进行了特内里费岛红外偏振仪。观测结果表明，在存在磁场的情况下，由散射过程产生的线性偏振分布。经过仔细的数据减少，我们证明了极不对称的斯托克斯V型配置文件中的针状材料，我们能够建模与两个磁性组件沿视线，并在原子取向的存在下，在能级，引起多重态的存在。我们讨论了一些可能的情况下，可以产生的原子取向的针状。我们强调整个肢体的分光偏振观测的重要性，以区分这些信号从观测文物。
英文摘要：
We report Stokes vector observations of solar spicules and a prominence in the He I 1083 nm multiplet carried out with the Tenerife Infrared Polarimeter. The observations show linear polarization profiles that are produced by scattering processes in the presence of a magnetic field. After a careful data reduction, we demonstrate the existence of extremely asymmetric Stokes V profiles in the spicular material that we are able to model with two magnetic components along the line of sight, and under the presence of atomic orientation in the energy levels that give rise to the multiplet. We discuss some possible scenarios that can generate the atomic orientation in spicules. We stress the importance of spectropolarimetric observations across the limb to distinguish such signals from observational artifacts.
