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 ...
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. ...
Are anomalous cosmic rays the main contribution to the low-energy galactic cosmic ray spectrum?
(IOP Publishing, 2008)
While the high-energy part of the Galactic cosmic ray spectrum is well observed, its nature at energies below
about 1 GeV nucleon-1 is still not known well. Recent in situ measurements made with the Voyager 1 spacecraft
in ...
On cosmic ray modulation beyond the heliopause: where is the modulation boundary?
(IOP Publishing, 2011)
Two of the paradigms in modeling the transport of galactic cosmic rays are that the modulation boundary is the heliopause and that the local interstellar spectra are identical to the galactic cosmic ray spectra. Here we ...
Longitudinal variation of the pickup-proton-injection efficiency and rate at the heliospheric termination shock
(EDP Sciences, 2008)
Context. Pickup ions are considered to be the seed population of the anomalous cosmic rays. The acceleration of the pickup ions at the solar wind termination shock depends on the efficiency with which they are injected ...
Origin of the differential fluxes of low-energy electrons in the inner heliosheath
(IOP, 2017)
The study addresses the question of the origin of low-energy electrons measured by Voyager 1 in the multi-keV
range in the inner heliosheath. It intends to demonstrate that the observed keV-fluxes of electrons are ...
