日出Ca II H观测中针状体盘上对应物的可能识别

Probable identification of the on-disk counterpart of spicules in Hinode Ca II H observations

A. G. de Wijn

摘要:

我提出了一个高分辨率的时间序列的Ca II H图像和Fe I 630.15 nm的光谱与太阳光学望远镜的日之出航天器上采取的研究。Ca II H和Fe I线的核心强度之间有很好的对应关系,除了在前者的网络场浓度周围的微弱发射,在后者是不存在的。对盘上观测的分析和与临边观测的比较表明,这种“网络薄雾”对应于针状体,特别是可能是II型针状体。他们被称为出现在排放在磁盘上的宽带钙II H诊断和网络的阴霾是最强的,在这些地区的功能类似于II型针状在模拟中产生。

英文摘要:

I present a study of high-resolution time series of Ca II H images and Fe I 630.15 nm spectra taken with the Solar Optical Telescope on the Hinode spacecraft. There is excellent correspondence between the Ca II H and Fe I line core intensity, except tenuous emission around the network field concentrations in the former that is absent in the latter. Analysis of on-disk observations and a comparison with limb observations suggests that this "network haze" corresponds to spicules, and likely to type-II spicules in particular. They are known to appear in emission in on-disk broadband Ca II H diagnostics and the network haze is strongest in those areas where features similar to type-II spicules are produced in simulations.
