Modelling anomalous cosmic ray oxygen in the heliosheath
(EDP Sciences, 2010)
This paper discusses a numerical modulation model to describe anomalous cosmic ray acceleration and transport in the heliosheath, the portion of the heliosphere between the termination shock and the heliopause. The model ...
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 ...
Modeling the modulation of galactic and jovian electrons by stochastic processes
(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 ...
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 ...
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 ...
A generalized diffusion tensor for fully anisotropic diffusion of energetic particles in the heliospheric magnetic field
(IOP Publishing, 2012)
The spatial diffusion of cosmic rays in turbulent magnetic fields can, in the most general case, be fully anisotropic, i.e., one has to distinguish three diffusion axes in a local, field-aligned frame. We reexamine the ...
Is the highest cosmic-ray flux yet to come?
(Springer, 2014)
The recent 2009 solar-minimum period was characterized by a record-setting high
Galactic cosmic-ray flux observed at Earth. This, along with the unexpected low heliospheric
magnetic-field magnitude, caused this period ...
Where does the heliospheric modulation of galactic cosmic rays start?
(Elsevier, 2014)
The long outstanding question of where the heliospheric (solar) modulation of galactic cosmic rays actually begins, in terms of spatial
position, as well as at what high kinetic energy, can now be answered. Both answers ...
Modelling heliospheric current sheet drift in stochastic cosmic ray transport models
(Springer, 2012)
Drifts are one of the major cosmic ray modulation mechanisms in the heliosphere. Three types of drifts occur in the background heliospheric magnetic field, namely curvature, gradient and current sheet drifts. The last ...
