Long-term variation in cosmic-ray modulation
(North-West University (South Africa), 2017)The transport of cosmic rays inside the heliosphere can be described b the Parker equation (Parker, 1965). Since there are no full analytica solutions to the Parker equation, two first-order approximate solutions o the ... -
Numerical modeling of the evolution of stellar wind cavities and supernova remnants
(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 ... -
Time dependence of the flux of helium nuclei in cosmic rays measured by the PAMELA experiment between 2006 July and 2009 December
(IOP, 2020)Precise time-dependent measurements of the Z = 2 component in the cosmic radiation provide crucial information about the propagation of charged particles through the heliosphere. The PAMELA experiment, with its long flight ...
