论文摘要
在冠状明亮点和在活跃区域的太阳耀斑中检测到了移动结构，这些区域是双向，对称，同时和准周期性的（Ning＆Guo 2014; Ning 2016; Li等人2016a）。它们可以被视为通过磁重新连接血浆流出的观察性证据。在本文中，我们探索了15个紫外线（UBP）中的一对移动结构，这些结构在2020年11月19日在宁静的阳光下或在一个小的活跃地区内观察到，并通过高分辨率（HRI）望远镜（hri）望远镜（hri）望远镜（EUI）的高分辨率（EUI）（EUI）在两种太阳能或solo and solo and solo and pass and bands and band and bands and pass and yrie and yrie and。 Å。在十个UBP中观察到的移动结构从它们的明亮核心开始，并向两端传播，被解释为双向移动结构的分化运动。这些运动结构的特征也具有同时性和对称性，在七个UBP的情况下，它们表现出了准周期性。磁重连接后可以通过流出产生它们。在另外五个UBP中看到的移动结构源自双端并靠近移动并合并在一起，表现为收敛运动，这可能是由于通过磁重新连接的流入而引起的，或者可能被解释为由成色层蒸发驱动的上流。
Moving structures have been detected in coronal bright points and in a solar flare in active regions, which were bi-directional, symmetrical, simultaneous, and quasi-periodic (Ning & Guo 2014; Ning 2016; Li et al. 2016a). They could be regarded as observational evidence of plasma outflows via magnetic reconnection. In this article, we explored pairs of moving structures in fifteen ultraviolet bright points (UBPs), which were observed in the quiet Sun or inside a small active region on 19 November 2020, and measured by the High Resolution (HRI) Telescopes of the Extreme Ultraviolet Imager (EUI) on board the Solar Orbiter (SolO) in two passbands, HRIEUV 174 Å and HRILyα 1216 Å. Moving structures observed in ten UBPs as starting from their bright cores and propagating toward two ends, are interpreted as diverging motions of bi-directional moving structures. These moving structures are also characterized by simultaneity and symmetry and in the case of seven UBPs they exhibit quasi-periodicity. They could be generated by outflows after magnetic reconnections. Moving structures seen in another five UBPs as originating from double ends and moving closer, and merging together, are manifested as converging motions, which might be caused by inflows through the magnetic reconnection, or might be interpreted as upflows driven by the chromospheric evaporation.
