一个裸太阳黑子的磁拓扑：它真的是裸的吗？
Magnetic topology of a naked sunspot: Is it really naked?
摘要：
Hinode仪器实现的高空间、时间和光谱分辨率使人们能够更好地了解一些难以捉摸的太阳特征的行为，如气孔和裸露的太阳黑子。它们的快速进化以及在某些情况下它们的小尺寸使它们的研究变得困难。移动的磁性特征，尽管是更动态的结构，在过去的40年中已经被研究。它们总是与太阳黑子联系在一起，特别是与半影。然而，最近对一个裸黑子（没有半影的黑子）的观测显示出了MMF的活动。本报告观察结果的作者对将双极MMF活动解释为半影丝延伸至护城河持保留意见。当半影不存在时，这种类型的MMF如何存在？在本文中，我们研究了完整的磁场和（水平）速度拓扑结构相同的裸太阳黑子，显示如何存在的磁场拓扑结构类似于在太阳黑子中观察到的可以解释这些MMF，即使当强度图的裸太阳黑子不显示半影。
英文摘要：
The high spatial, temporal and spectral resolution achieved by Hinode instruments give much better understanding of the behavior of some elusive solar features, such as pores and naked sunspots. Their fast evolution and, in some cases, their small sizes have made their study difficult. The moving magnetic features, despite being more dynamic structures, have been studied during the last 40 years. They have been always associated with sunspots, especially with the penumbra. However, a recent observation of a naked sunspot (one with no penumbra) has shown MMF activity. The authors of this reported observation expressed their reservations about the explanation given to the bipolar MMF activity as an extension of the penumbral filaments into the moat. How can this type of MMFs exist when a penumbra does not? In this paper, we study the full magnetic and (horizontal) velocity topology of the same naked sunspot, showing how the existence of a magnetic field topology similar to that observed in sunspots can explain these MMFs, even when the intensity map of the naked sunspot does not show a penumbra.
