A New Explanation of Solar Radio Millisecond ``Spikes''
Abstract
The study proposes an explanation for solar radio spikes that involves an electromagnetic instability in fast electrons at a frequency of greater than 2 Omega (Omega = cyclotron frequency), so that the radiation can escape, and in which the unstable anisotropy is easily regenerated. The instability occurs after scattering of an electron beam by Langmuir waves. The radiation grows best along surfaces of constant magnetic field strength and has very narrow intrinsic bandwidth.
