论文摘要
在这项研究中，我们研究了太阳周期最大的黑子之一的血浆组合物的空间分布24。观察光球，色球球和电晕的观察结果与太阳早光的磁场建模汇总在一起，以探测调节不同连接群体中的等化性水平程度的条件。我们发现，在黑子蒙布拉上方的冠状磁场中，等离子体具有光球体组成。植根于半肿的冠状环包含分离的等离子体，在活动区域内连接的环中观察到最高水平。从染色体中检测到的磁性链接中检测到的磁性波动的位置，从磁力片段中检测到它们是磁连接的。这些结果表明，黑子色球活性与可观察到的冠状血浆组成变化之间的联系。
In this study, we investigate the spatial distribution of highly varying plasma composition around one of the largest sunspots of solar cycle 24. Observations of the photosphere, chromosphere, and corona are brought together with magnetic field modelling of the sunspot in order to probe the conditions which regulate the degree of plasma fractionation within loop populations of differing connectivities. We find that in the coronal magnetic field above the sunspot umbra, the plasma has photospheric composition. Coronal loops rooted in the penumbra contain fractionated plasma, with the highest levels observed in the loops that connect within the active region. Tracing field lines from regions of fractionated plasma in the corona to locations of Alfvenic fluctuations detected in the chromosphere shows that they are magnetically linked. These results indicate a connection between sunspot chromospheric activity and observable changes in coronal plasma composition.
