The effect of a dynamic inner heliosheath thickness on cosmic-ray modulation
(IOP Publishing, 2015)
The time-dependent modulation of galactic cosmic rays in the heliosphere is studied over different polarity cycles by
computing 2.5 GV proton intensities using a two-dimensional, time-dependent modulationmodel. By ...
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 ...
Modulation of galactic cosmic ray protons and electrons during an unusual solar minimum
(IOP Publishing, 2009)
During the latest Ulysses out-of-ecliptic orbit the solar wind density, pressure, and magnetic field strength have been the lowest ever observed in the history of space exploration. Since cosmic ray particles respond to ...
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, ...
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 ...
Cosmic ray modulation in the outer heliosphere: predictions for cosmic ray intensities up to the heliopause along Voyager 1 and 2 trajectories
(Elsevier, 2011)
Time dependent cosmic ray modulation in the outer heliosphere is calculated and results are compared to Voyager 1 and 2 observations using a two-dimensional time-dependent cosmic ray transport model. We predict possible ...
Galactic cosmic rays in the outer heliosphere: theory and models
(Springer, 2011)
We review recent advances in the field of galactic cosmic ray transport in the distant heliosphere. The advent of globalMHD models brought about a better understanding of the three-dimensional structure of the interface ...
Possible evidence for a Fisk-type heliospheric magnetic field. 1. Analyzing Ulysses/Ket electron observations
(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 ...
Modeling ground and space based cosmic ray observations
(Elsevier, 2012)
After entering our local astrosphere (called the heliosphere), galactic cosmic rays, as charged particles, are affected by the Sun’s turbulent magnetic field. This causes their intensities to decrease towards the inner ...
The heliospheric transport and modulation of multiple charged anomalous oxygen revisited
(EDP Sciences, 2010)
Context. Since the crossings of the solar wind termination shock by the Voyager 1 and 2 spacecraft, much speculation has surrounded the acceleration mechanism and region where the anomalous cosmic ray component is accelerated. ...
