离肢骨针的磁场

On the magnetic field of off-limb spicules

R. Centeno, J. Trujillo Bueno, A. Asensio Ramos

摘要:

确定与太阳针状体有关的磁场对于开发这些等离子体射流的适当模型至关重要,这些等离子体射流被认为在色球层的热,动力和磁结构中起着关键作用。在这里,我们报告的磁特性的离肢针状体在一个非常安静的区域的太阳大气中,推断出新的光谱偏振观测的He I 10830 A三重态与特内里费岛红外偏振仪。我们已经使用了一种新的反演代码的斯托克斯配置文件所造成的联合行动的原子级极化和汉勒和塞曼效应(HAZEL)来解释的观察。在狭缝的非常局部的区域中检测到强至~ 40 G的磁场,这可能代表有组织的网络针状物的场强的可能较低值。

英文摘要:

Determining the magnetic field related to solar spicules is vital for developing adequate models of these plasma jets, which are thought to play a key role in the thermal, dynamic and magnetic structure of the Chromosphere. Here we report on the magnetic properties of off-limb spicules in a very quiet region of the solar atmosphere, as inferred from new spectropolarimetric observations in the He I 10830 A triplet obtained with the Tenerife Infrared Polarimeter. We have used a novel inversion code for Stokes profiles caused by the joint action of atomic level polarization and the Hanle and Zeeman effects (HAZEL) to interpret the observations. Magnetic fields as strong as ~40G were detected in a very localized area of the slit, which could represent a possible lower value of the field strength of organized network spicules.
