    • Acceleration of cosmic rays in the outer heliosphere 

      Prinsloo, Phillip Lourens (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 ...
    • Aspects of the modulation of cosmic rays in the outer heliosphere 

      Ngobeni, Mabedle Donald (North-West University, 2006)
      A time-dependent two-dimensional (2D) modulation model including drifts, the solar wind tennination shock (TS) with diffusive shock acceleration and a heliosheath based on the Parker (1965) transport equation is used to ...
    • Effects of termination shock acceleration on cosmic rays in the heliosphere 

      Langner, Ulrich Wilhelm (North-West University, 2004)
      The interest in the role of the solar wind termination shock (TS) and heliosheath in cosmic ray (CR) modulation studies has increased sigm6cantly as the Voyager 1 and 2 spacecraft approach the estimated position of the TS. ...
    • Modeling of galactic cosmic rays in the heliosphere 

      Ngobeni, Mabedle Donald (2015)
      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 ...
    • Modelling of the heliosphere and cosmic ray transport 

      Snyman, Jasper Lodewyk (North-West University, 2007)
      A two dimensional hydrodynamic model describing the solar wind interaction with the local interstellar medium, which surrounds the solar system, is used to study the heliosphere both as a steady-state- and dynamic structure. ...
    • Numerical modelling of stellar winds for supernova progenitors 

      Van den Heever, Stefanus Petrus (North-West University, 2011)
      A two-dimensional hydrodynamic numerical model is extended and applied to simulate the interaction between stellar winds and the interstellar medium (ISM). In particular, the stellar wind evolution of O- and B-type stars ...
