Aspects of the time-dependent modulation of galactic cosmic rays throughout a three-dimensional heliosphere
(North-West University (South Africa), 2021)A dominant feature in the heliosphere is the heliospheric current sheet, separating regions of opposite polarity of the heliospheric magnetic field. This structure is dependent on solar activity through the tilt angle, ... -
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 ... -
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, ... -
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 ... -
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 ...
