Modelling of galactic and jovian electrons in the heliosphere
(North-West University, 2004)
A three-dimensional (3D) steady-state electron modulation model based on Parker (1965) transport equation is applied to study the modelling of – 7 MeV galactic and Jovian electrons in the inner
heliosphere. The latter ...
Modelling of galactic cosmic ray electrons in the heliosphere
(North-West University, 2012)
The Voyager 1 spacecraft is now about 25 AU beyond the heliospheric termination shock and
soon it should encounter the outer boundary of the heliosphere, the heliopause. This is set to
be at 120 AU in the modulation model ...
A study of cosmic ray anisotropies in the heliosphere
(North-West University, 2006)
The three-dimensional (3D) steady-state electron modulation model of Ferreira (2002),
based on Parker (1965) transport equation, is used to study the modulation of the 7 MeV
galactic and Jovian electron anisotropies in ...
Cosmic ray modulation processes in the heliosphere
(North-West University, 2011)
The solar minimum of 2009 has been identified as an exceptional event with regard to
cosmic ray (CR)modulation, since conditions in the heliosphere have reached unprecedented
quiet levels. This unique minimum has been ...
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 ...
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 ...
