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 …

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 …

This article reviews the theory of the kinetic (cyclotron an synchroton) maser instabilities. The
subject has been extensively developed in recent years by many authors, who have been …

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 …

Decimetric radio events with large numbers of spikes during the impulsive phase of flares
have been selected. In the observing range of 100 to 1000 MHz some flares have of the …

We calculate and compare the temporal growth rate and the number of e‐folding growths for
the following wave modes due to a loss‐cone‐driven cyclotron maser: fundamental x, o, and …

We offer a coherent plasma-emission mechanism for intense microwave radiation of a flare
in the impulsive phase. The radiation arises because of a loss-cone instability of plasma …

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' …
