    • 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 ...

    • Cosmic rays in the dynamic heliosheath 

      Ferreira, S.E.S.; Potgieter, M.S.; Scherer, K. (Elsevier, 2008)
      Cosmic ray modulation in the outer heliosphere is discussed from a modeling perspective. Emphasis is on the transport and acceleration of these particles at and beyond the solar wind termination shock in the inner heliosheath ...

    • Cosmic rays in the dynamic heliosphere 

      Potgieter, Marius S. (Japan Society of Plasma Science and Nuclear Fusion Research, 2009)
      he relation between the dynamics of the heliosphere, its shape and geometry, so lar activity and cosmic ray variations is addressed. The global features of the helio sphere influence what happens inside its boundaries ...

    • 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 ...
