We trace the evolution of research on extreme solar and solar-terrestrial events from the
1859 Carrington event to the rapid development of the last twenty years. Our focus is on the …

In this review we focus on the fundamental theory of magnetohydrodynamic reconnection,
together with applications to understanding a wide range of dynamic processes in the solar …

Stellar flares are characterized by sudden enhancement of electromagnetic radiation in
stellar atmospheres. So far, much of our understanding of stellar flares has come from …

Context. Stellar coronal mass ejections (CMEs) are the primary driver of exoplanetary space
weather and may affect the habitability of exoplanets. However, detections of possible stellar …

Partial filament eruptions have often been observed; however, the physical mechanisms that
lead to filament splitting are not yet fully understood. In this study, we present a unique event …

Solar flares fall into two types, with eruptive ones associated with coronal mass ejection
(CME) and confined ones without CME. To explore whether there are preflare conditions in …

Violent solar flares and coronal mass ejections (CMEs) are magnetic phenomena. However,
how magnetic fields reconnecting in the flare differ from nonflaring magnetic fields remains …

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 …

A solar spot group with a large area is not a requirement for a great magnetic storm. Nearly
half (14/30) of all storms with a minimum Dst value≤− 300 nT from 1932–2014 originated in …

Flares, sometimes accompanied by coronal mass ejections (CMEs), are the result of sudden
changes in the magnetic field of stars with high energy release through magnetic …
