Research Overview:

Dr. Duan studies the solar eruptions with observational data and MHD simulations. It is well known that solar eruptions are essentially sudden, explosive releases of the magnetic energy in the solar corona. Thus, to reveal the mechanism of the solar eruptions, one must fully understand the 3D structures and topologies of the coronal magnetic field closely prior to eruptions. Currently, she is devoted to a systematical study of the structures of the pre-eruption magnetic fields as well as the triggering mechanism of eruptions. Based on multi-instrument data analysis, she has collected a sufficiently large set of eruption events. With nonlinear force-free coronal magnetic extrapolation model and magnetic topology analysis method, she has statistically surveyed the 3D structures of the magnetic fields in the active regions immediately before solar eruptions, attempting to find out the key parameters that quantify the intensities and instabilities of these structures, as well as their relations with solar eruptions. In the near future, Dr. Duan plans to analyze the pre-eruption magnetic fields with data-driven MHD simulation, in order to further improve the understanding of pre-eruption magnetic structures and triggering mechanisms, which could ultimately be applied to the prediction of solar eruption for the aim of accurate and quantitative forecasting of space weather.
