A comparative study of cosmic ray modulation models
(North-West University, 2015)Until recently, numerical modulation models for the solar modulation of cosmic rays have been based primarily on finite difference approaches; however, models based on the solution of an appropriate set of stochastic ... -
Cosmic ray modulation with a Fisk-type heliospheric magnetic field and a latitude-dependent solar wind speed
(Elsevier, 2009)The effect of a latitude-dependent solar wind speed on a Fisk heliospheric magnetic field [Fisk, L. A. Motion of the footpoints of heliospheric magnetic field lines at the Sun: implications for recurrent energetic particle ... -
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 ... -
A multi-wavelength approach to solar energetic particle transport using remote sensing and in-situ observations
(North-West University (South Africa), 2022)Space weather (SWx) studies and the development of SWx prediction models have gained significant momentum in the last few years. Large SWx events have the potential to incapacitate technological infrastructure, both on ... -
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 ... -
The effects of magnetic field modifications on the solar modulation of cosmic rays with a SDE-based model
(Elsevier, 2016)A numerical model for the solar modulation of cosmic rays, based on the solution of a set of stochastic differential equations (SDEs), is used to illustrate the effects of modifying the heliospheric magnetic field, ...
