Abstract High time and spectral-resolution polarimeter observations between 24 and 37 MHz show many solar bursts with complex fine structure. Some Type III bursts resolve into intermediate-drift, narrow- band, unpolarized, circularly or linearly polarized subbursts; others appear to be unstructured, with little or moderate polarization. The few Type II and Type IV bursts that we have thus far recorded are unpolarized. Circularly polarized Type I bursts and reverse-drift pairs appear occasionally during decametric continuum events; concurrent Type III's are structured. We infer then that the corona has much fine structure, with numerous plasma and hydromagnetic waves as well as shocks, and particle streams Publication: The Astrophysical Journal Pub Date: November 1969 DOI: 10.1086/180446 Bibcode: 1969ApJ...158L.123W full text sources ADS |
