Three known examples of coherent emission in radio astronomical sources are reviewed:
plasma emission, electron cyclotron maser emission (ECME) and pulsar radio emission …

The auroral zone ionosphere is coupled to the outer magnetosphere by means of field-
aligned currents. Parallel electric fields associated with these currents are now widely …

We have developed an auroral precipitation model which separately categorizes the
discrete aurora and both the electron and ion diffuse aurora. The discrete aurora includes …

Small-amplitude double layers and solitary waves containing magnetic-field-aligned electric
field components have been observed for the first time in the auroral plasma between …

We review both observational and theoretical aspects of the generation of auroral radio
emissions at the outer planets, trying to organize the former in a coherent frame set by the …

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 …

The wave instrument on the Swedish Viking satellite performed measurements of plasma
density and potential fluctuations with high temporal and spatial resolution. In the auroral …

We present evidence based on measurements from the Polar spacecraft for the existence of
small‐scale, large‐amplitude kinetic Alfvén waves/spikes at the plasma sheet boundary …

Electric field and energetic particle observations by the Fast Auroral Snapshot (FAST)
satellite provide convincing evidence of particle acceleration by quasi‐static, magnetic‐field …

Abstract The Polar Satellite carries the first three-axis electric field detector flown in the
magnetosphere. Its direct measurement of electric field components perpendicular and …
