A comparative study of cosmic ray modulation models
(North-West University, 2015)
Until recently, numerical modulation models for the solar modulation of cosmic rays have
been based primarily on finite difference approaches; however, models based on the solution
of an appropriate set of stochastic ...
Acceleration of cosmic rays in the outer heliosphere
(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 ...
