    • Long-term variation in cosmic-ray modulation 

      Mosotho, Moshe Godfrey (North-West University (South Africa), 2017)
      The transport of cosmic rays inside the heliosphere can be described b the Parker equation (Parker, 1965). Since there are no full analytica solutions to the Parker equation, two first-order approximate solutions o the ...
    • Numerical modeling of the evolution of stellar wind cavities and supernova remnants 

      Van der Schyff, Augusts Eric (North-West University, Potchefstroom Campus, 2016)
      An astrosphere is a low density cavity that results from an outflowing supersonic wind. Of particular interest in this study is the effect of radiative cooling on the computed evolution of astrospheres created by O and ...
