Analysis of powerful local acceleration of solar wind particles

Abstract

Collisionless plasma of the solar wind is considered. A number of physical processes in this plasma lead to the formation of magnetic islands that are potential traps for charged particles. The merging and contractions of magnetic islands cause a powerful acceleration of these particles to energies over 1 MeV. This work continues the study in recent years on modeling of the acceleration of charged particles of the solar wind. Our analytical solution of the transport equations allowed us to find the exact number of particles with energies exceeding given level.
