Thermal Cyclotron Radiation from Solar Active Regions,

Abstract

Spectra with fine structure resulting from the thermal cyclotron radio emission from solar active regions are discussed. Source conditions (distribution of magnetic field and kinetic temperature with height) are suggested which would cause the spectrum to take the form of a set of cyclotron lines and high-frequency cut-offs. Each distribution results in a characteristic spectrum and polarization. This permits one to deduce the conditions in the source through the properties of the observed microwave solar radio emission. To obtain reliable data on the fine structure and judge conditions in the sources it is necessary to study microwave solar radio emission with swept-frequency or multi-channel receivers and highly directional antennae.
