One of the longstanding questions of space science is: How does the Earth's
magnetosphere generate auroral arcs? A related question is: What form of energy is …

The present 15th volume of the ISSI Space Science Series is devoted to Auroral Plasma
Physics. The aurora is arguably the most intriguing phenomenon in space plasma physics …

An overview of the plasma environment near the earth is provided. We describe how the
near-earth plasma is formed, including photo-ionization from solar photons and impact …

A statistical study has been made of dynamic small‐scale auroral events in order to
understand the drivers of the large variability in the electrodynamics of auroral arcs at fine …

In data mining, density-based clustering, which entails classifying datapoints according to
their distributions in some space, is an essential method to extract information from large …

The paper reviews generator processes and configurations of six types of auroral arcs:
embedded arcs, Alfvénic arcs, onset arcs, poleward arcs during substorms, auroral …

Unstable field-aligned currents are seen as the origin of field-aligned potential drops. They
convert energy stored in magnetic shear stresses into kinetic energy. A good fraction of this …

The combination of high time and space resolution measurements in the magnetic zenith
(optical and radar) and detailed modeling of the ionospheric response to auroral particle …

Suprathermal electron bursts (STEBs), characterized by a board energy spectrum and a field‐
aligned pitch angle distribution, have been well recognized to be associated with electron …

The formation of dispersive Alfvén resonance layers is investigated using a three‐
dimensional, two‐fluid, magnetically incompressible model, including electron inertia and …
