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 ...
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. ...
A study of the time-dependent modulation of cosmic rays in the inner heliosphere
(North-West University, 2010)
A two-dimensional (2-D) time-dependent cosmic ray modulation model is used to calculate the modulation of cosmic-ray protons and electrons for 11-and 22-year modulation cycles using a compound approach to describe solar ...
Cosmic ray modulation processes in the heliosphere
(North-West University, 2011)
The solar minimum of 2009 has been identified as an exceptional event with regard to
cosmic ray (CR)modulation, since conditions in the heliosphere have reached unprecedented
quiet levels. This unique minimum has been ...
Modelling charge-sign dependent modulation of cosmic rays in the heliosphere
(North-West University (South Africa), 2016)
The solar minimum of cycle 23/24 has seen exceptionally quiet levels of solar activity
and heliospheric modulation, which resulted in the highest cosmic ray (CR) spectrum
ever recorded at Earth in December 2009 by the ...
The modulation of galactic cosmic rays over a solar cycle
(North-West University (South Africa), 2016)
This work studied the modulation of galactic cosmic rays in the heliosphere by using a well-established,
time dependent numerical modulation model to calculate cosmic ray transport
inside the heliosphere over a solar ...
