Radio astronomy of the sun has reached a high level of maturity, while radio astronomy of
the stars is now a burgeoning new field of study. The present review is mainly concerned …

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

▪ Abstract Radio emission from solar flares offers a number of unique diagnostic tools to
address long-standing questions about energy release, plasma heating, particle …

We present results from the most comprehensive radio monitoring campaign towards the
closest star to our Sun, Proxima Centauri. We report 1.1–3.1 GHz observations with the …

Millisecond spikes of the solar radio emission are known for more than two decades. They
have recently seen a surge in interest of theoreticians who are fascinated by their high …

The generation of continuum bursts from the sun at dm and m wavelengths (in particular,
type IV bursts) via the electron-cyclotron-maser instability is examined. The maser instability …

This review covers fairly comprehensively experimental and theoretical research on the fine
structure of types zebra pattern (ZP) and fiber bursts (FB) in solar type II+ IV radio bursts. The …

Currently available models of one of the most intriguing types of unsteady rf solar emission,
millisecond solar radio spikes, are discussed. A comparative analysis of the models' …

The presence of a large-scale surface magnetic field in early-type stars leads to several
unique electromagnetic phenomena producing radiation over X-ray to radio bands. Among …

The loss-cone instability of energetic electrons at double plasma resonance is considered.
Conditions required for the formation of a zebra pattern in type IV solar radio bursts are …
