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 ...
An investigation into a generalized Fisk-type heliospheric magnetic field
(North-West University (South Africa), Potchefstroom Campus, 2016)
The existence of a Fisk-type heliospheric magnetic field (HMF) has been contested since the Fisk field [Fisk, 1996] challenged the traditional view of the HMF first proposed by Parker . Several modifications of the ...
The effect of a Fisk-Parker hybrid magnetic field on cosmic rays in the heliosphere
(North-West University, 2005)
The existence of a Fisk-type heliospheric magnetic field (HMF) is one of the most debated questions in cosmic-ray modulation. Recently, Burger and Hitge  developed a divergence-free Fisk-Parker hybrid magnetic field ...
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] ...
