Solar eruptive phenomena embrace a variety of eruptions, including flares, solar energetic
particles, and radio bursts. Since the vast majority of these are associated with the eruption …

Solar flares are observed at all wavelengths from decameter radio waves to gamma-rays
beyond 1 GeV. This review focuses on recent observations in EUV, soft and hard X-rays …

We have evaluated the energetics of 38 solar eruptive events observed by a variety of
spacecraft instruments between 2002 February and 2006 December, as accurately as the …

We present an overview of solar flares and associated phenomena, drawing upon a wide
range of observational data primarily from the RHESSI era. Following an introductory …

Abstract Solar Energetic Particles (SEPs) are an important component of Space Weather,
including radiation hazard to humans and electronic equipment, and the ionisation of the …

Solar flares occur in complex sunspot groups, but it remains unclear how the probability of
producing a flare of a given magnitude relates to the characteristics of the sunspot group …

We present a homogeneous analysis of line and continuum emission from simultaneous
high-cadence spectra and photometry covering near-ultraviolet and optical wavelengths for …

Context. The standard CSHKP model for eruptive flares is two-dimensional. Yet
observational interpretations of photospheric currents in pre-eruptive sigmoids, shear in post …

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 flare on the Sun was observed exactly 150 years ago. During most of the long
history, only secondary effects have been noticed, so flares remained a riddle. Now the …
