    • A comparative study of cosmic ray modulation models 

      Raath, Jan Louis (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 ...

    • A stochastic approach to the modelling of cosmic rays in the heliosphere 

      Raath, Jan Louis (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 ...
