Coronal mass ejections (CMEs) are the largest-scale eruptive phenomenon in the solar
system, expanding from active region-sized nonpotential magnetic structure to a much larger …

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 …

We present observations of the magnetic field configuration and its transformation in six
solar eruptive events that show good agreement with the standard bipolar model for eruptive …

Solar eruptions are spectacular magnetic explosions in the Sun's corona, and how they are
initiated remains unclear. Prevailing theories often rely on special magnetic topologies that …

This chapter provides an overview of current efforts in the theory and modeling of CMEs.
Five key areas are discussed:(1) CME initiation;(2) CME evolution and propagation;(3) the …

We review the physical processes of particle acceleration, injection, propagation, trap**,
and energy loss in solar flare conditions. An understanding of these basic physical …

This review article summarizes the advancement in the studies of Earth-affecting solar
transients in the last decade that encompasses most of solar cycle 24. It is a part of the effort …

We have investigated the onset and acceleration of coronal mass ejections (CMEs) and
eruptive flares. To isolate the eruption physics, our study uses the breakout model, which is …

Flare ribbons are commonly attributed to the low-altitude impact, along the footprints of
separatrices or quasi-separatrix layers (QSLs), of particle beams accelerated through …

We review basic theoretical concepts in particle acceleration, with particular emphasis on
processes likely to occur in regions of magnetic reconnection. Several new developments …
