Solar Energetic Particle Driven Alfvén Wave Growth and Consequences
Abstract
Our model shows that in large solar energetic particle (SEP) events, streaming protons amplify interplanetary (IP) Alfv´n waves by orders of magnitude near e the Sun. The wave intensity varies strongly and non-monotonically in wavenumb er, time, and space. It falls steeply with distance and may be difficult to observe at 1 AU. Wave amplification dynamically modifies the rigidity and radial dependence of SEP scattering and throttles SEP transport. It is essential in understanding the time and energy variations of SEP elemental abundances.
