An improved treatment of neutral sheet drift in the inner heliosphere
(IOP, 2019)Drifts due to the curvature and gradients in the heliospheric magnetic field, as well as along the heliospheric current sheet, have long been known to play a significant role in the transport of galactic cosmic rays. ... -
Modelling of solar energetic particles by stochastic processes
(North-West University (South Africa), 2019)The focused transport of solar energetic particles has received increasingly more interest in the last couple of years due to upcoming missions to the Sun. Stochastic differential equations offer a numerically robust way ... -
Modelling the perpendicular transport of energetic electrons in the inner heliosphere
(North-West University (South Africa), 2023)The transport of charged particles across a background magnetic field can occur through either particle drifts or perpendicular diffusion caused by magnetic turbulence. The former process, which was proposed by some as an ... -
A multi-wavelength approach to solar energetic particle transport using remote sensing and in-situ observations
(North-West University (South Africa), 2022)Space weather (SWx) studies and the development of SWx prediction models have gained significant momentum in the last few years. Large SWx events have the potential to incapacitate technological infrastructure, both on ... -
Numerical investigation of solar energetic particle transport between the Sun, Earth, and Mars
(North-West University (South Africa), 2019)Solar energetic particles pose a danger to spacecraft electronics, and even more significantly, to a future spacecraft crew beyond the Earth’s magnetosphere. Given the current NASA and SpaceX interest in interplanetary ... -
On the pitch-angle-dependent perpendicular diffusion coefficients of solar energetic protons in the inner heliosphere
(IOP Publishing, 2019)Various numerical solar energetic particle (SEP) transport studies have shown that perpendicular diffusion plays a significant role in the propagation of these particles in the heliosphere. In particular, computed SEP ... -
On the shape of SEP electron spectra: the role of interplanetary transport
(IOP Science, 2020)We address the effect of particle scattering on the energy spectra of solar energetic electron events using (i) an observational and (ii) a modeling approach. (i) We statistically study observations of the STEREO spacecraft, ...
