标题： The Observations of Magnetic Reconnection During the Interaction Process of Two Active Region Filaments

摘要： 我们研究了2023年5月9日活动区（AR）NOAA 13296和NOAA 13293中两条磁流管（F1和F2）之间的相互作用及其随后的磁重联现象，利用了太阳动力学天文台、新真空太阳望远镜以及中国H{\alpha }太阳探测器提供的高时空分辨率和多波段观测数据。 由正极性（P1）运动驱动的F1从东南向西北移动，导致与F2发生碰撞并重联。 这一重联交换了它们的足点，形成了两个新的磁流管（F3和F4），符合“弹弓”型磁流管相互作用类型。 在相互作用过程中，观察到了由于F1运动而移动的电流片以及沿F3和F4运动的重联喷流。 在“弹弓”型磁流管相互作用中很少能观测到电流片，其长度约为2.17兆米，宽度约为0.84兆米。 相互作用后，F1消失，而部分F2残留，表明这种相互作用涉及部分“弹弓”重联，原因是磁流管间的磁通量不相等。 F2的剩余部分将在同一相互作用区域内与连接极性N1和P1的磁环发生另一次磁重联。 由重联产生的物质不断注入F4，导致其最终形态。 这些发现增强了我们对“弹弓”型磁流管相互作用的理解，表明磁流管之间可能存在更多部分“弹弓”重联事件，而非完整的“弹弓”事件。 显示英文摘要

摘要： We investigate the interaction between two filaments (F1 and F2) and their subsequent magnetic reconnection in active region (AR) NOAA 13296 and AR NOAA 13293 on May 9, 2023, utilizing high spatial and temporal resolution and multi-wavelength observational data from the Solar Dynamics Observatory, the New Vacuum Solar Telescope, and the Chinese H{\alpha} Solar Explorer. The movement of F1 from the southeast toward the northwest, driven by the motion of the positive magnetic polarity (P1), leads to a collision and reconnection with F2. This reconnection exchanges their footpoints, resulting in the formation of two new filaments (F3 and F4) consistent with "slingshot" type filament interaction. During the interaction, the current sheet moving due to the motion of F1 and the reconnection outflows moving along F3 and F4 were both observed. The current sheet is rarely observed in the slingshot type filament interaction, measuring approximately 2.17 Mm in length and 0.84 Mm in width. After the interaction, the F1 disappears whereas a portion of F2 remains, indicating that the interaction involves partial slingshot reconnection, due to the unequal magnetic flux between the filaments. The residual part of F2 will undergo another magnetic reconnection in the same interaction region with the magnetic loops connecting polarities N1 and P1. The material generated by the reconnection is continuously injected into F4, leading to its final morphology. The findings enhance our understanding of slingshot-type filament interactions, indicating that partial slingshot reconnections between filaments may be more common than full slingshot events.
