Summary:
This proposal addresses Focused Science Topic 3(b): Use Inner Heliospheric Observations to better constrain Coronal Mass Ejection (CME) and Solar Energetic Particle (SEP) Event Models. We will develop a model to study in detail the interplanetary transport and acceleration of multi-species solar energetic particles (SEPs) at a CME-driven shock that propagates from the solar corona to > 1 AU. The non-linear time-dependent model will include self-consistent interaction between SEPs and Alfv n waves, using a pitch-angle dependent resonance condition. For SEPs, the model will include focusing, convection, adiabatic deceleration, pitch-angle scattering, and momentum diffusion. Treatment of Alfv n waves will include propagation, SEP-driven growth/damping, shock transmission, and cascading.Performance Year | Reference | Investigation Type | Actions |
