The effect of the heliospheric current sheet on cosmic-ray modulation
(North-West University (South Africa), Potchefstroom Campus, 2015)
The heliospheric current sheet is a dominant feature of the heliosphere. As solar activity increases, the tilt angle of the current sheet increases, and so does the region swept out by this structure, to cover most of ...
On the development and applications of a three–dimensional ab initio cosmic–ray modulation model
(North-West University, 2012)
A proper understanding of the effects of turbulence on the diffusion and drift of cosmic-rays in the heliosphere is imperative for a better understanding of cosmic-ray modulation. This study presents an ab initio model ...
An ab initio approach to the heliospheric modulation of galactic cosmic rays
(North-West University, 2006)
In the present study we aim to further our understanding of charged particle transport in a magnetized medium. To this end, we perform direct numerical simulations of particle transport in a turbulent magnetic field. From ...
On the heliospheric diffusion tensor and its effect on 26-day recurrent cosmic-ray variations
(North-West University, 2008)
A first attempt at an ab initio steady-state three-dimensional modulation model for galactic cosmic ray electrons, utilizing expressions adapted from the work of Teufel and Schlickeiser  and Shalchi et al. [2004a] ...
