Cyclotron Instability in Solar Flares

Research output: Contribution to journalArticlepeer-review


The properties of the cyclotron-maser radiation generated by anisotropic distributions of fast electrons with power-law momentum distributions are studied. The momentum and pitch-angle distributions of the electrons are chosen with regard to available observational constraints. The results obtained for these model distributions are compared with those in the literature for other distributions. The dependence of the properties of the cyclotron instability on the parameters of the distribution of fast electrons is analyzed. These properties are in good quantitative agreement with observational data on millisecond solar radio spikes.
