Polarisation structure of Jupiter's decametre radio bursts

Abstract

THE high-resolution dynamic spectra of Jupiter's decameter radio emission exhibit structures consisting of repeated tilted ridges1. The frequency–time slope of these ‘diagonal patterns’ also referred to as modulation lanes varies from 50 to 300 kHz s−1. The slope is a function of the System III central meridian longitude of Jupiter and it may be either positive or negative2,3. Recent observations of modulation lanes are described by Ellis4,5 and Lecacheux6. Here I report a study of polarisation diversity in the spectra of modulation lanes.
