Modeling of electrons in the heliosphere
(North-West University (South Africa), Potchefstroom Campus, 2016)
The propagation and modulation of electrons in the heliosphere play an important part in
improving our understanding and assessment of the processes of solar modulation. A locally
developed, full three-dimensional, ...
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 ...
An investigation into a generalized Fisk-type heliospheric magnetic field
(North-West University (South Africa), Potchefstroom Campus, 2016)
The existence of a Fisk-type heliospheric magnetic field (HMF) has been contested since the
Fisk field [Fisk, 1996] challenged the traditional view of the HMF first proposed by Parker
[1958]. Several modifications of the ...
Modelling charge-sign dependent modulation of cosmic rays in the heliosphere
(North-West University (South Africa), 2016)
The solar minimum of cycle 23/24 has seen exceptionally quiet levels of solar activity
and heliospheric modulation, which resulted in the highest cosmic ray (CR) spectrum
ever recorded at Earth in December 2009 by the ...
The modulation of galactic cosmic rays over a solar cycle
(North-West University (South Africa), 2016)
This work studied the modulation of galactic cosmic rays in the heliosphere by using a well-established,
time dependent numerical modulation model to calculate cosmic ray transport
inside the heliosphere over a solar ...
