本文利用Sunrise III/SUSI观测到太阳临边外Ca II K发射延伸至6 Mm,发现模拟虽能产生该发射但光谱宽度偏低,需更精细建模。

中文摘要 AI 辅助

Sunrise III/SUSI仪器对Ca II K线核心的临边外发射进行了定点凝视观测,结合了优异的时间分辨率和光谱分辨率。该发射延伸至太阳临边以上6 Mm处,表明存在类似于针状体的临边外结构。在本文中,我们描述了观测到的发射的空间-光谱特性,重点关注Sunrise III/SUSI所分辨出的谱线形状细节,并将观测结果与基于太阳色球层数值模拟的简单模型进行比较。我们发现,该模拟在Mm高度处包含足够多的冷而密的物质以产生临边外发射,但这些特征的光谱宽度略低于观测值,因此需要更详细的建模。

英文摘要

The Sunrise III/SUSI instrument performed a sit-and-stare observation of the off-limb emission in the Ca II K line core, with a combination of excellent temporal and spectral resolution. The emission reaches up to 6 Mm above the solar limb, indicating the existence of off-limb structures akin to spicules. In this letter, we describe the spatio-spectral properties of the observed emission, focusing on the spectral line shape resolved in detail by Sunrise III/SUSI, and compare the observation with simple modeling that relies on a numerical simulation of the solar chromosphere. We find that the simulation contains enough cool and dense material at Mm heights to produce off-limb emission, but that the spectral width of these features is slightly lower than observed, necessitating more detailed modeling.
