Large Amplitude Low Frequency Waves in a Magnetized Nonuniform Electron–Positron–Ion Plasma

Abstract

It is shown that the large amplitude low-frequency electromagnetic drift waves in electron–positron–ion plasmas might give rise to dipolar vortices. A linear dispersion relation of several coupled electrostatic and electromagnetic low-frequency modes is obtained. The relevance of this work to both laboratory and astrophysical situations is pointed out.
