ISEE-3 spacecraft observation of 120 relatively simple, isolated bursts in the 30-1980 kHz range are the basis of the present study of Type III bursts in the solar wind. Several characteristics are identified for many of these bursts which imply that the mode of emission changes from predominantly fundamental plasma radiation during the rise phase to predominantly second harmonic during decay. The fundamental emission begins in time coincidence with the start of Langmuir waves, confirming the conventional belief in these waves' causation of Type III bursts. Attention is given to the characteristics of fundamental components, by comparison to harmonics, at km-wavelengths.read more

Coherent emission mechanisms in astrophysical plasmas
TL;DR: The early development and subsequent refinements of coherent emission theory, motivated by application to solar radio bursts, are reviewed in this article, and a possible direct measure of coherence is pointed out.

A new method for studying remote type II radio emissions from coronal mass ejection‐driven shocks
TL;DR: In this article, the authors used dynamic spectra of the radio intensity plotted as a function of inverse frequency and time to track the CME-associated radio emissions in the interplanetary medium.
