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 ...
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 ...
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 ...
A study of the global heliospheric modulation of galactic carbon
(Elsevier, 2014)
Observations of galactic Carbon in the heliosphere provide a useful tool with which a comprehensive description of the global
modulation of cosmic rays both inside and outside off the solar wind termination shock (TS) can ...
The charge-sign dependent effect in the solar modulation of cosmic rays
(Elsevier, 2014)
The centennial anniversary of the discovery of cosmic rays was in 2012. Since this discovery considerable progress has been made on
several aspects related to galactic cosmic rays in the heliosphere. It is known that they ...
