Collisionless Dynamics of the Magnetosphere

Abstract

Our research program (1) demonstrated the relationship between the spectrum and intensity of low-frequency fluctuations and the collisionless transport of energetic trapped particles, (2) verified the applicability of the guiding-center drift Hamiltonian as the foundation for numerical simulation of driven particle flows, (3) derived a unified analytical theory of the electron and ion tearing instability in the presence of all three components of the tail magnetic field in order to identify a trigger for substorms, and (4) investigated the effect of small but finite resistivity on the dynamics of current-sheet formation in the solar corona. All topics originally proposed for study have been addressed by our studies and published within archival journals. In addition, our research uncovered entirely new topics of investigation which are the subject of new and separately funded research activities.
