一个有源区暗条的形成和演化

Formation and evolution of an active region filament

C. Kuckein, R. Centeno, V. Martínez Pillet

摘要:

在文献中可以找到解释细丝如何形成的几种方案。在本文中,我们分析了活动区灯丝的观测,并在当前灯丝形成模型的背景下对观测到的特性进行了严格的评估。这项研究是基于多高度分光偏振观测。推断的矢量磁场是从光球层或色球层开始外推的。分析了位于盘中心附近的暗条的视线运动,并由此推导出多普勒速度。我们的结论是,一部分的磁结构出现在光球下面。

英文摘要:

Several scenarios explaining how filaments are formed can be found in literature. In this paper, we analyzed the observations of an active region filament and critically evaluated the observed properties in the context of current filament formation models. This study is based on multi-height spectropolarimetric observations. The inferred vector magnetic field has been extrapolated starting either from the photosphere or from the chromosphere. The line-of-sight motions of the filament, which was located near disk center, have been analyzed inferring the Doppler velocities. We conclude that a part of the magnetic structure emerged from below the photosphere.
