Acceleration of galactic electrons at the solar wind termination shock and Voyager 1 observations
Potgieter, Marius S.; Prinsloo, P. Lourens; Strauss, R. Du Toit (PoS, 2017)Diffusive shock acceleration (DSA) , as an acceleration process for G alactic electrons at the solar wind termination shock (TS) , is investigated with a comprehensive numerical model which ... -
Comparison of astrospheres around cool and hot stars
Scherer, K.; Ferreira, S.E.S.; Strauss, R.D.; Bomans, D.J.; Fichtner, H. (IOP Publishing, 2016)Simulations of astrospheres around hot and cool stars have recently move into the focus of scientific research. We describe here the differences between the astrospheres around hot and cool stars. While those around the ... -
Extracting the February 1956 ground level enhancement event from legacy cosmic ray recordings
Mattana, V.W.F.; Drevin, G.R.; Strauss, R.D. (Springer, 2018)Early continuous recordings of cosmic rays, as measured with Carnegie Type C Ionization Chambers, were made on rolls of photographic paper. This paper describes the extraction of the ionization data of the February 1956 ... -

Mattana, Vincent; Drevin, Günther; Strauss, Du Toit (IEEE, 2018)Early continuous recordings of cosmic rays, as measured with Carnegie Type C Ionization Chambers, were made on rolls of photographic paper. This paper describes the extraction of the ionization data of a ground level ... -
Perpendicular diffusion of solar energetic particles: when is the diffusion approximation valid?
Strauss, R.D.; Van den Berg, J.P.; Steyn, P.J.; Effenberger, F.J.; Wijsen, N. (IOP Publishing, 2020)Multi-spacecraft observations of widespread solar energetic particle (SEP) events indicate that perpendicular (to the mean field) diffusion is an important SEP transport mechanism. However, this is in direct contrast to ... -
Sunspot identification and tracking with OpenCV
Du Toit, Ruben; Drevin, Günther; Maree, Nicolaas; Strauss, Du Toit (IEEE, 2020)Space weather forecasting has gained interest over the past five decades since mankind started exploring space and began using highly developed technology. Dangers such as coronal mass ejections (CME) can negatively affect ...
