Recent data and theory for type II solar radio bursts are reviewed, focusing on a recent
analytic quantitative theory for interplanetary type II bursts. The theory addresses electron …

Context. During solar flares a large amount of energy is suddenly released and partly
transferred into energetic electrons. They are of special interest since a substantial part of …

Shock waves are associated with multiple powerful coherent radio emissions within the
heliosphere and local interstellar medium. The radio emissions definitely driven by shocks …

We investigate the causes of variations in interplanetary type II radio bursts using an analytic
model which predicts the emission generated by electron beams in the foreshock regions …

Type II radio bursts drift in frequency as shock waves and coronal mass ejections (CMEs)
move through the Sun's corona and the solar wind. This paper extends the theoretical …

We discuss a new acceleration or energization mechanism of charged particles in space
and astrophysical plasmas. In the presence of an electrostatic potential gradient and a …

Quasilinear-based simulations are presented for the effects on coronal type III bursts of
spatially varying ion temperature T i in the corona. The simulations use a newly developed …

High‐intensity radio emission events at 2–3 kHz were observed by the Voyager spacecraft
during 1983–1984 and 1992–1993. Such events are thought to occur when shock waves …

Some type III bursts are observed to undergo sudden flux modifications, eg, reductions and
intensifications, when type III beams cross shocks in the upper corona or solar wind. First …

We present detailed quantitative results from a theoretical model for fundamental (fp) and
second harmonic (2fp) radio emission generated in Earth's foreshock by beam‐driven …
