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 ...
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 ...
Acceleration of cosmic rays in the outer heliosphere
(North-West University (South Africa), Potchefstroom Campus, 2016)
Shortly before the Voyager spacecraft crossed the heliospheric termination shock, they encountered narrow, peak-like enhancements in the intensities of low-energy electrons. These enhancements were associated at the time ...
Modeling of galactic cosmic rays in the heliosphere
The modulation of galactic cosmic ray (GCR) Carbon in a north-south asymmetrical heliosphere is studied, using a two-dimensional numerical model that contains a solar wind termination shock (TS), a heliosheath, as well as ...
A stochastic approach to the modelling of cosmic rays in the heliosphere
(North-West University (South Africa), 2020)
A spatially three-dimensional numerical modulation model based on solving a set of stochastic differential equations, corresponding to the Parker transport equation, is employed to study the galactic proton spectra measured ...
