The polarization of "herring-bone" features in solar radio bursts of spectral type II

Abstract

The degree and phase of polarization of short-lived features in solar radio emission of spectral type II is investigated. It is found that although the type II burst is in general weakly or negligibly polarized it may contain highly polarized elements. In particular, the fast-frequency drifting features that appear to diverge from a type II burst ("herring-bone" features) are at, times found to exhibit strong circular polarization.
