Data-driven modeling of solar coronal magnetic field evolution and eruptions
Magnetic fields play a fundamental role in the structure and dynamics of the solar corona. As
they are driven by their footpoint motions on the solar surface, which transport energy from …

A model of failed solar eruption initiated and destructed by magnetic reconnection
Solar eruptions are explosive disruption of coronal magnetic fields, and often launch coronal
mass ejections into the interplanetary space. Intriguingly, many solar eruptions fail to escape …

Photospheric signatures of CME onset
Coronal mass ejections (CMEs) are solar eruptions that involve large-scale changes to the
magnetic topology of an active region. There exists a range of models for CME onset which …
