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 ...
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 [2004] developed a divergence-free Fisk-Parker hybrid magnetic field ...
Effects of termination shock acceleration on cosmic rays in the heliosphere
(North-West University, 2004)
The interest in the role of the solar wind termination shock (TS) and heliosheath in cosmic ray (CR) modulation studies has increased sigm6cantly as the Voyager 1 and 2 spacecraft approach the estimated position of the TS. ...
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 [2003] and Shalchi et al. [2004a] ...
