Circular-ribbon flares and the related activities

Zhang, Qingmin

Solar flares are an impulsive increase of emissions as a result of impetuous release of magnetic free energy. This paper will present the recent progress on circular-ribbon flares (CRFs) and their related activities, including coronal jets, filaments, coronal mass ejections (CMEs), radio bursts, coronal dimmings, and coronal loop oscillations. Owi…

Recent advances in solar data-driven MHD simulations of the formation and evolution of CME flux ropes

Poedts, Stefaan; Schmieder, Brigitte; Guo, Jinhan

Filament eruptions and coronal mass ejections are physical phenomena related to magnetic flux ropes carrying electric current. A magnetic flux rope is a key structure for solar eruptions, and when it carries a southward magnetic field component when propagating to the Earth. It is the primary driver of strong geomagnetic storms. As a result, devel…
