Modelling of galactic cosmic ray electrons in the heliosphere
(North-West University, 2012)
The Voyager 1 spacecraft is now about 25 AU beyond the heliospheric termination shock and
soon it should encounter the outer boundary of the heliosphere, the heliopause. This is set to
be at 120 AU in the modulation model ...
Time–dependent modulation of cosmic rays in the outer heliosphere
(North-West University, 2013)
The time-dependent modulation of galactic cosmic rays in the heliosphere is studied by computing
intensities using a two-dimensional, time-dependent modulation model. The compound
approach of Ferreira and Potgieter (2004), ...
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 ...
Modelling of cosmic ray modulation in the heliosphere by stochastic processes
(North-West University, 2013)
The transport of cosmic rays in the heliosphere is studied by making use of a newly developed
modulation model. This model employes stochastic differential equations to numerically solve
the relevant transport equation, ...
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 ...
Particle acceleration at travelling shocks in the heliosphere
(North-West University (South Africa), 2020)
The acceleration of energetic protons from the solar wind (SW) distribution by traveling interplanetary
shocks is investigated. The SW velocity distribution is represented using kappa functions, which are transformed in ...
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 ...
