半影精细结构的CRISP偏振光谱成像
CRISP Spectropolarimetric Imaging of Penumbral Fine Structure
摘要：
我们讨论半影精细结构中的一小部分孔，观察与CRISP成像分光偏振仪在瑞典1米太阳望远镜（SST），接近其衍射极限0.16弧秒。Milne-Eddington反演应用到这些斯托克斯数据揭示了暗芯半影侵入体和暗芯光桥的场强和倾斜角的大变化。这个半影结构的中外部显示出0.3弧秒宽的脊，间隔1.6弧秒（1200公里），并与30度的倾角变化相关。在这些脊之间，没有小规模的磁结构，可以很容易地识别与个别通量管。在两个棘突之间的中间，可以看到一个垂直度增加了近10度且磁场较弱的结构。这个结构与最亮的半影灯丝是同空间的，可能表明对流上升流的位置。
英文摘要：
We discuss penumbral fine structure in a small part of a pore, observed with the CRISP imaging spectropolarimeter at the Swedish 1-m Solar Telescope (SST), close to its diffraction limit of 0.16 arcsec. Milne-Eddington inversions applied to these Stokes data reveal large variations of field strength and inclination angle over dark-cored penumbral intrusions and a dark-cored light bridge. The mid-outer part of this penumbra structure shows 0.3 arcsec wide spines, separated by 1.6 arcsec (1200 km) and associated with 30 deg inclination variations. Between these spines, there are no small-scale magnetic structures that easily can be be identified with individual flux tubes. A structure with nearly 10 deg more vertical and weaker magnetic field is seen midways between two spines. This structure is co-spatial with the brightest penumbral filament, possibly indicating the location of a convective upflow from below.
