Structure and Evolution of Filament Channels

研究人员正在对细丝通道中磁场的结构和动力学，特别是轴向磁场的起源进行一系列的观测和理论研究。他们使用几个地面和天基观测望远镜，研究太阳上灯丝通道内和周围的磁场特征和等离子体流动。他们正在寻找在极性反转线附近出现或取消的小规模偶极磁重联的证据。此外，他们还试图推导出日冕和日冕附近观测到的细丝通道的轴向场，以及高纬度的细丝通道和细丝的演化，以及极冠的形成。最后，他们使用卫星数据来研究磁重联在建立日冕和日冕拱形中观测到的全球螺旋度模式中的作用。

Investigators are performing a series of observational and theoretical programs on the structure and dynamics of magnetic fields in filament channels, particularly the origin of the axial field. Using several ground- and space-based observational telescopes, they study magnetic features and plasma flows in and around filament channels on the Sun. They are searching for evidence of magnetic reconnection in small-scale emerging or canceling bipoles near polarity inversion lines. In addition, they seek to deduce axial fields in prominences and filament channels observed near the limb, as well as the evolution of filament channels and filaments at high latitude, and the formation of the polar crowns. Finally, they use satellite data to study the role of magnetic reconnection in establishing observed global patterns of helicity in prominences and coronal arcades.
