Solar Flares and Coronal Mass Ejections

Title:

Description:

Solar eruptions, in the forms of solar flares and coronal mass ejections (CMEs), are the most energetic phenomena in the solar system. Solar eruptions are the driver of severe space weather that may affect satellite operation, communication, navigation and other advanced modern technological systems. In this talk, I will introduce the physical mechanisms of solar eruptions, with a focus on two contrasting paradigms: the non-ideal MHD process of magnetic reconnection versus the ideal process of magnetic flux rope instability. I will present the state-of-the-art observations of solar eruptions from the advanced Solar Dynamic Observatory (SDO) spacecraft. The observational evidence of the existence of magnetic flux ropes (MFRs) will be presented. The morphological, dynamic and thermal properties of magnetic flux ropes and driven CMEs will be discussed.
