EVIDENCE FOR WIND-LIKE REGIONS, ACCELERATION OF SHOCKS IN THE DEEP CORONA, AND RELEVANCE OF 1/f DYNAMIC SPECTRA TO CORONAL TYPE II BURSTS

摘要

Type II radio bursts are produced near the local plasma frequency f_p and near 2f_p by shocks moving through the corona and solar wind. In the present Letter eight well-defined coronal type II radio bursts (30-300 MHz) are analyzed. Three results are pres
