Abstract:
When crossing the termination shock (TS), Voyager 1 and 2 observed Anomalous Cosmic Rays (ACRs) different as expected by diffusive shock acceleration. In this work, we study the ACRs acceleration by analyzing test particles trajectories fromnumerical solution of Newton-Lorentz equation. As a preliminary work, simple toy models of plasma, magnetic field, and TS are assumed. In addition, our modeling results of ACRs spectra will be compared with Voyager 1 and 2 observations.
