    • Cosmic ray flux anisotropies caused by astrospheres 

      Scherer, K.; Strauss, R.D.; Ferreira, S.E.S.; Fichtner, H. (Elsevier, 2016)
      Huge astrospheres or stellar wind bubbles influence the propagation of cosmic rays at energies up to the TeV range and can act as small-scale sinks decreasing the cosmic ray flux. We model such a sink (in 2D) by a sphere ...

    • Numerical modeling of the evolution of stellar wind cavities and supernova remnants 

      Van der Schyff, Augusts Eric (North-West University, Potchefstroom Campus, 2016)
      An astrosphere is a low density cavity that results from an outflowing supersonic wind. Of particular interest in this study is the effect of radiative cooling on the computed evolution of astrospheres created by O and ...

    • The numerical simulation of astrospheric evolution in different interstellar environments 

      Marais, Andrea (North-West University (South Africa), 2023)
      The interaction between the interstellar medium (ISM) and a stellar wind leads to the formation of an astrosphere. In this study, the evolution of astrospheres is simulated with a two-dimensional spherical hydrodynamic ...
