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 ...
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 ...
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 ...
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 ...
