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…

Propagation characteristics of coronal mass ejections (CMEs) in the corona and interplanetary space

Wang, Yuming; Shen, Fang; Shen, Chenglong +3 more

Coronal mass ejections (CMEs) play an important role in space weather. The propagation characteristics of CMEs in the Corona and interplanetary space determine whether, when and how the CME will hit the Earth. To this end, a lot of progress has been made both on observational and numerical studies of CMEs. With the development of the advanced obse…
