Wave Generation in the Transport of Particles from Large Solar Flares
Abstract
The growth rate of Alfven waves produced by energetic solar protons streaming outward from large solar flares is estimated. The mathematical development is directly analogous to that used to describe the self-containment of cosmic rays in the Galaxy. It is found that sufficient intensities of streaming protons can generate Alfven waves that reduce the scattering mean free path of the particles that produce the waves. This scattering impedes further flow of particles. The estimated growth rate of the waves depends linearly upon the particle intensity so that lower energy particles are much more strongly affected than high-energy particles for typical solar spectra.
