Areas of Interest:

Evolution of solar active regions; formation, evolution and eruption of coronal flux ropes; origin and eruption characteristics of solar flares and coronal mass ejections.

 

Research Overview:

Dr. Liu is a solar physicist. Her research focuses on the evolution of solar active region magnetic field, formation and evolution of coronal flux ropes, and the origin of solar flares and coronal mass ejections etc., aiming at extending our knowledge about the origin and trigger of solar eruptions.  Until now, she and her colleagues found that the source active regions of confined flares usually possessed weak non-potentiality at the core region, and strong confinement of overlying field above the core region; she also discovered the rapid buildup process of the magnetic flux rope in constructed coronal magnetic field of confined flare, and validated the “collisional shearing” mechanism of major solar eruptions in emerging active regions from a statistical perspective.
