标题： Prominence Formation Associated with an Emerging Helical Flux Rope

摘要： 太阳耀斑的形成和演化过程及磁配置仍不清楚。 为了研究耀斑的形成过程，我们利用太阳光学望远镜对 NOAA AR 10953 中的一个耀斑进行了\emph{日出}卫星的连续观测。 正如我们之前的一封信中所报告的，我们发现了一个迹象，表明一个螺旋状通量环从光球层以下的预存耀斑下方出现。 在这里，我们研究了 emerging 螺旋状通量环的更详细特性及其光球指示，并讨论它们与耀斑形成的关系。 我们的主要结论是：(1) 一个缺乏强垂直磁场的暗区在 Ca\textsc{二}H 线滤光器图像中变宽然后变窄。 这一现象与光球对应的螺旋状通量环的出现一致。 通量环的大小大约为 30,000 公里长和 10,000 公里宽。 宽度大于耀斑的宽度。 (2) 没有检测到剪切运动或汇聚流，但我们发现在极性反转线附近存在发散流，如中粒度结构。 中粒度结构的存在可能与螺旋状通量环的出现有关。 (3) 出现的螺旋状通量环与预存耀斑的磁场重新连接，以稳定耀斑数天。 因此，我们推测耀斑日冕磁场以螺旋状通量环的形式出现，这有助于耀斑的形成和维持。 显示英文摘要

摘要： The formation and evolution process and magnetic configuration of solar prominences remain unclear. In order to study the formation process of prominences, we examine continuous observations of a prominence in NOAA AR 10953 with the Solar Optical Telescope on the \emph{Hinode} satellite. As reported in our previous Letter, we find a signature suggesting that a helical flux rope emerges from below the photosphere under a pre-existing prominence. Here we investigate more detailed properties and photospheric indications of the emerging helical flux rope, and discuss their relationship to the formation of the prominence. Our main conclusions are: (1) A dark region with absence of strong vertical magnetic fields broadens and then narrows in Ca \textsc{ii} H-line filtergrams. This phenomenon is consistent with the emergence of the helical flux rope as photospheric counterparts. The size of the flux rope is roughly 30,000 km long and 10,000 km wide. The width is larger than that of the prominence. (2) No shear motion or converging flows are detected, but we find diverging flows such as mesogranules along the polarity inversion line. The presence of mesogranules may be related to the emergence of the helical flux rope. (3) The emerging helical flux rope reconnects with magnetic fields of the pre-existing prominence to stabilize the prominence for the next several days. We thus conjecture that prominence coronal magnetic fields emerge in the form of helical flux ropes that contribute to the formation and maintenance of the prominence.
