    • Cosmic ray modulation beyond the heliopause: a hybrid modeling approach 

      Strauss, R.D.; Potgieter, M.S.; Ferreira, S. E. S.; Fichtner, H.; Scherer, K. (IOP Science, 2013)
      Results from a newly developed hybrid cosmic ray (CR) modulation model are presented. In this approach, the transport of CRs is computed by incorporating the plasma flow from a magnetohydrodynamic model for the heliospheric ...
    • Modeling the modulation of galactic and jovian electrons by stochastic processes 

      Kopp, Andreas; Potgieter, Marthinus Steenkamp; Strauss, Roelf Du Toit; Büsching, Ingo (IOP Publishing, 2011)
      We present a newly developed numerical modulation model to study the transport of galactic and Jovian electrons in the heliosphere. The model employs stochastic differential equations (SDEs) to solve the corresponding ...
    • A stochastic approach to galactic proton propagation: influence of the spiral arm structure 

      Kopp, A.; Büsching, I.; Potgieter, M.S.; Strauss, R.D. (Elsevier, 2014)
      A newly developed numerical code solving Fokker–Planck type transport equations in currently four dimensions (space plus momentum or energy) and time by means of stochastic differential equations (SDEs) is applied to the ...
    • Three-dimensional wavy heliospheric current sheet drifts 

      Burger, Renier Adriaan; Clem, J.; Pei, C.; Bieber, J.W. (IOP publishing, 2012)
      We present an analytic method to determine the directions of the three-dimensional (3D) heliospheric current sheet (HCS) drift for any tilt angle based on Parker's heliospheric magnetic field and compare it with published ...
