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 …

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 …

Of all electrons, runaway electrons have long been recognized in the fusion community as a
distinctive population. They now attract special attention as a part of ITER mission …

In the standard model of solar flares, a large-scale reconnection current sheet is postulated
to be the central engine for powering the flare energy release,–and accelerating particles …

For the first time it is experimentally demonstrated on the JET tokamak that a combination of
a low impurity concentration bulk plasma and large magnetohydrodynamic instabilities is …

In this chapter, we review some features of particle acceleration in astrophysical jets. We
begin by describing four observational results relating to the topic, with particular emphasis …

It turned out to be really a rare and happy occasion to know exactly when and how a new
branch of space physics was born, namely, a physics of solar cosmic rays. It happened on …

Despite the significant progress achieved in recent years, the physical mechanisms
underlying the origin of solar energetic particles (SEPs) are still a matter of debate. The …

Increases of ion fluxes in the keV–MeV range are sometimes observed near the heliospheric
current sheet (HCS) during periods when other sources are absent. These resemble solar …

Current state-of-the-art spectrographs cannot resolve the fundamental spatial
(subarcseconds) and temporal (less than a few tens of seconds) scales of the coronal …
