Solving Parker’s transport equation with stochastic differential equations on GPUs
(Elsevier, 2015)
The numerical solution of transport equations for energetic charged particles in space is generally very costly in terms of time. Besides the use of multi-core CPUs and computer clusters in order to decrease the computation ...
Modelling the effects of scattering parameters on particle-drift in the solar modulation of galactic cosmic rays
(Elsevier, 2015)
It is well known that particle drift motions are suppressed by diffusive scattering as established by direct numerical simulations. The effect of constant scattering on the drift velocities of charged particles has always ...
A local interstellar spectrum for galactic electrons
(Elsevier, 2013)
A heliopause spectrum at 122 AU from the Sun is presented for galactic electrons over an energy range
from 1 MeV to 50 GeV that can be considered the lowest possible local interstellar spectrum (LIS). The
focus of this ...
On the propagation times and energy losses of cosmic rays in the heliosphere
(American Geophysical Union, 2011)
We present calculations of the propagation times and energy losses of cosmic rays as they are transported through the heliosphere. By calculating these quantities for a spatially 1D scenario, we benchmark our numerical ...
Modelling and observing Jovian electron propagation times in the inner heliosphere
(Elsevier, 2013)
The propagation of Jovian electrons in interplanetary space was modelled by solving the relevant transport equation numerically through the use of stochastic differential equations. This approach allows us to calculate, ...
New insights from modeling the neutral heliospheric current sheet
(Springer, 2015)
Recently, the modulation of cosmic rays in the heliosphere
has increasingly been studied by solving the well
known transport equation via an approach based on stochastic
differential equations. This approach, which is ...
Modulation of galactic cosmic rays in a north-south asymmetrical heliosphere
(Elsevier, 2011)
Observations made with the two Voyager spacecraft confirmed that the solar wind decelerates to form the heliospheric termination shock. Voyager 1 crossed this termination shock at ∼94 AU in 2004, while Voyager 2 crossed ...
Modelling of low-energy galactic electrons in the heliosheath
(Elsevier, 2011)
The modulation of cosmic ray electrons in the heliosphere plays an important role in improving our understanding and assessment of the processes applicable to low-energy galactic electrons. A full three-dimensional numerical ...
Time-dependent cosmic ray modulation
(Elsevier, 2011)
Time-dependent cosmic ray modulation is calculated over multiple solar cycles using our well established two-dimensional time-dependent modulation model. Results are compared to Voyager 1, Ulysses and IMP cosmic ray ...
The solar modulation of electrons in the heliosphere
(Springer Link, 2013)
The propagation and modulation of electrons in
the heliosphere play an important part in improving our understanding
and assessment of the modulation processes.
A full three-dimensional numerical model is used to ...
