    • 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 ...
    • The dynamic heliosphere, solar activity, and cosmic rays 

      Potgieter, Marius S. (Elsevier, 2010)
      This brief review addresses the relation between solar activity, cosmic ray variations and the dynamics of the heliosphere. The global features of the heliosphere influence what happens inside its boundaries on a variety ...
    • Modelling of galactic carbon in an asymmetrical heliosphere: effects of asymmetrical modulation conditions 

      Ngobeni, M.D.; Potgieter, M.S. (Elsevier, 2012)
      Observations of galactic cosmic rays (GCRs) from the two Voyager spacecraft inside the heliosheath indicate significant differences between them, suggesting that in addition to a possible global asymmetry in the north–south ...
    • Solar cycle variations and cosmic rays 

      Potgieter, M.S. (Elsevier, 2008)
      Cosmic rays are excellent indicators of the various solar cycle variations. Galactic and anomalous cosmic rays encounter an outward moving solar wind with cyclic magnetic-field fluctuations and turbulence, which constitute ...
