    • 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 galactic cosmic ray electrons in the heliosphere 

      Nndanganeni, Rendani Rejoyce (North-West University, 2012)
      The Voyager 1 spacecraft is now about 25 AU beyond the heliospheric termination shock and soon it should encounter the outer boundary of the heliosphere, the heliopause. This is set to be at 120 AU in the modulation model ...
