A self-consistent model for the acceleration of solar-wind protons and generation of Alfvën turbulence by an interplanetary shock wave
Abstract
The self-consistent non-stationary theory for the acceleration of solar wind protons and the excitation of Alfven waves by the traveling shocks had been investigated. It was shown that the self-consisitent spectra of the accelerated particles and Alfven waves are governed not only by the current environment parameters but depend significantly on the history of the shock. If the superthermal particles injection rate to the acceleration process is decreasing with the geliocentric distance and/or sufficient generation of Alfven waves the energy spectrum and the spatial distribution became non-monotonic. The theory satisfactorily reproduces the measured energy and spatial distributions near the interplanetary shocks.
