Modeling the modulation of galactic and jovian electrons by stochastic processes

Kopp, Andreas; Potgieter, Marthinus Steenkamp; Strauss, Roelf Du Toit; Büsching, Ingo (IOP Publishing, 2011)

We present a newly developed numerical modulation model to study the transport of galactic and Jovian electrons in the heliosphere. The model employs stochastic differential equations (SDEs) to solve the corresponding ...
Possible evidence for a fisk-type heliospheric magnetic field, 1: analyzing Ulysses/Ket electron observations

Burger, Renier Adriaan; Engelbrecht, Nicholas Eugene; Ferreira, Stephanus Esaias Salomon; Potgieter, Marthinus Steenkamp; Sternal, O.; Fichtner, H.; Heber, B.; Kopp, A.; Scherer, K. (IOP Publishing, 2011)

The propagation of energetic charged particles in the heliospheric magnetic field is one of the fundamental problems in heliophysics. In particular, the structure of the heliospheric magnetic field remains an unsolved ...
