DOI: 10.1002/2016ja023592
Abstract: The effects of the leading edge stream interface of high-speed solar-wind streams (HSSs) upon the Earth's magnetosphere have been extensively documented. The arrival of HSSs leads to significant changes in the plasmasphere, plasma sheet, ring… read more here.

DOI: 10.1002/2016ja023656
Abstract: Field-aligned beams of suprathermal electrons, known as strahl, are a frequently observed constituent of solar wind plasma. However, the formation and interplanetary evolution of the strahl electron populations has yet to be fully understood. As… read more here.

DOI: 10.1002/2017gl072676
Abstract: The nonlinear response of the cross polar cap potential (CPCP) to solar wind driving electric field is a well-known phenomenon. The reasons behind this saturation, however, are still under debate. We have performed a statistical… read more here.
