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 …

The phenomenon of quasi-periodic pulsations (QPPs) in solar and stellar flares has been
known for over 50 years and significant progress has been made in this research area. It has …

The Sun is magnetically active and often produces eruptive events on different energetic
and temporal scales. Until recently, the upper limit of such events was unknown and …

The Sun, as an active star, is the driver of energetic phenomena that structure interplanetary
space and affect planetary atmospheres. The effects of Space Weather on Earth and the …

We present results from a set of numerical simulations aimed at exploring the mechanism of
coronal mass ejection (CME) suppression in active stars by an overlying large-scale …

The first self-consistent simulations of electron acceleration during magnetic reconnection in
a macroscale system are presented. Consistent with solar flare observations, the spectra of …

The Carrington event in 1859, a solar flare with an associated geomagnetic storm, has
served as a prototype of possible superflare occurrence on the Sun. Recent geophysical …

Discovery of frequent superflares on active cool stars opened a new avenue in
understanding the properties of eruptive events and their impact on exoplanetary …

We conducted four-night multiwavelength observations of an active M-dwarf star EV
Lacertae on 2022 October 24–27 with simultaneous coverage of soft X-rays (NICER; 0.2–12 …

Solar flares may be the best-known examples of the explosive conversion of magnetic
energy into bulk motion, plasma heating, and particle acceleration via magnetic …
