讲座摘要

Magnetic reconnection is a fundamental physical process in various astrophysicalspace, and laboratory environments. In solar physics, it is even believed to be akey mechanism to heat/accelerate plasmas and drive the eruption of large-scalemagnetic field, giving rise to coronal mass ejections, flares, and solar energeticparticles. For my talk, l will first present imaging observations of magneticreconnection during solar explosive events emphasizing on its three-dimension(3D) confiquration and turbulent nature through high spatiotemporal resolutionand multiple perspective observations. Toward understanding the origin ofturbulent reconnection, in particular its physical links to flare dynamical structuresof different scales, our group recently implemented high-resolution MHDsimulation of 3D magnetic reconnection in a realistic flare configuration. Thesecond part of my talk will show simulation results and prospects for the future.
