1. 学术报告：Magnetic reconnection in the solar corona When：3月21日（周一）上午10点 Where：教学行政楼1514会议室 Who：美国NJIT  刘睿 博士 Title：Magnetic reconnection in the solar corona Abstract: As one of the fundamental processes in plasma, magnetic reconnection is the most plausible mechanism responsible for powering the large-scale, eruptive phenomena in the solar atmosphere, such as flares and coronal mass ejections (CMEs). It has been suggested that solar eruptions sometimes proceed in a two-stage fashion. At first highly sheared fields reconnect to form a flux rope, and then its buoyant rising stretches the overlying, less-sheared fields to form a Y-type current sheet underneath, where reconnections help the flux rope to blow out. Here I present the direct observational verification of the reconnection structure and dynamics at each stage, i.e., tether-cutting reconnection in the first stage and Y-type current sheet in the second. 欢迎大家参加。
