关于SOLIS观测的极场分布
On the Polar Field Distribution as Observed by SOLIS
摘要：
我们使用矢量磁谱仪（VSM）色球全磁盘磁图，从天气光学长期调查的太阳（SOLIS）项目，研究极帽内的磁场通量浓度的分布。我们发现，磁通量元素优先出现在远离两极的极帽内的低纬度地区。这对许多太阳现象有影响，例如精细的极冠结构（即，极地羽流）。我们的结果也对从低纬度到高纬度携带磁通量的过程有影响（例如，循环）。
英文摘要：
We use Vector Spectromagnetograph (VSM) chromospheric full-disk magnetograms, from the Synoptic Optical Long-term Investigations of the Sun (SOLIS) project, to study the distribution of magnetic field flux concentrations within the polar caps. We find that magnetic flux elements preferentially appear toward lower latitudes within the polar caps away from the poles. This has implications on numerous solar phenomena such as the formation and evolution of fine polar coronal structures (i.e., polar plumes). Our results also have implications for the processes carrying the magnetic flux from low to high latitudes (e.g., meridional circulation).
