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 modulation of galactic cosmic-ray electrons in the heliosheath
(IOP Publishing, 2010)
Voyager 1 has observed strong increases in the intensities of 2-160 MeV electrons since crossing the termination shock of the heliosphere in 2004 December. Before this time these intensities were submerged below the detector ...
Current sheets, magnetic islands, and associated particle acceleration in the solar wind as observed by Ulysses near the ecliptic plane
(IOP Publishing, 2019)
Recent studies of particle acceleration in the heliosphere have revealed a new mechanism that can locally energize particles up to several MeV nucleon–1. Stream–stream interactions, as well as the heliospheric current sheet ...
The re-acceleration of galactic electrons at the heliospheric termination shock
(IOP Publishing, 2017)
Observations by the Voyager spacecraft in the outer heliosphere presented several challenges for the paradigm of diffusive shock acceleration (DSA) at the solar wind termination shock (TS). In this study, the viability of ...
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. ...
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 ...
