报告题目：The Role of Magnetic Flux Rope in Solar Eruptions and Space Weather
报 告 人：Prof. Jie Zhang George Mason University
摘 要：Solar eruptions, in the form of solar flares and coronal mass ejections (CMEs), are the most energetic phenomena in the solar system. Solar eruptions are also the driver of severe space weather that may affect satellite operation, communication, navigation and other advanced modern technological systems. Thus, the research of solar eruptions is not only of great scientific interest, but also has importance practical purposes. I will present the state-of-the-art observations of solar eruptions from SDO, STEREO and SOHO spacecraft. I will further discuss the physical mechanisms of solar eruptions, with a focus on the two contrasting paradigms: the non-ideal MHD process of magnetic reconnection versus the ideal process of flux rope instability. The observations and theory regarding the CME propagation in the interplanetary space will also be discussed.
