The Origin and Evolution of Core Magnetic Structures in Solar Eruptions
(SH030)

Convener: Jie Zhang, George Mason University Fairfax

Co-Conveners: Georgios Chintzoglou, University Corporation for Atmospheric Research

Description

Solar eruptions, manifested as erupting filaments, flares and CMEs, are the results of sudden and impulsive energy release in the Sun's corona. It is generally believed that solar eruptions are driven by the action of a core magnetic structure, which could be either in the form of a sheared magnetic arcade or a magnetic flux rope. This session is focused on research efforts that address the origin and creation of core magnetic structures and their evolution leading to eruptions. Recent advancements on this topic were mainly enabled by the joint analysis of vector magnetogram observations with HMI and multi-temperature coronal observations with AIA onboard the SDO spacecraft. Advancements in theoretical modeling and 3D numerical simulations have also provided new insights. The specific questions include (1) what is the key process of creating the core structure? (2) how does the core structure evolve in the corona in response to photospheric motions?
