Dissipation of the sectored heliospheric magnetic field near the heliopause: a mechanism for the generation of anomalous cosmic rays

, 2009
The recent observations of the anomalous cosmic ray (ACR) energy spectrum as Voyagers 1 and 2 crossed the heliospheric termination shock have called into question the conventional shock source of these energetic particles.

Study of pickup of cometary ions in turbulent solar winds [PDF]

The influence of moderately strong magnetic disturbances on the ion pickup process near a comet is studied by a test-particle method. The research is motivated by recent observations with ICE and Giotto at Giacobini-Zinner and Halley.

Density of neutral interstellar hydrogen at the termination shock from Ulysses pickup ion observations

, 2008
By reevaluating a 13-month stretch of Ulysses SWICS H pickup ion measurements near 5 AU close to the ecliptic right after the previous solar minimum, this paper presents a determination of the neutral interstellar H density at the solar wind termination ...

Convergent Heavy-ion Plume from the Martian Ionosphere

The Astrophysical Journal
Ion escape is a key consequence of the solar wind interaction with Mars, yet the three-dimensional structure of the heavy-ion plume, a major escape channel, remains poorly constrained.

Ion dynamics in quasi-perpendicular collisionless interplanetary shocks: A case study

Frontiers in Physics, 2013
Interplanetary shocks are believed to play an important role in the acceleration of charged particles in the heliosphere. While the acceleration to high energies proceeds via the diffusive mechanism at the scales exceeding by far the shock width, the ...

Solar wind He pickup ions as source of tens-of-keV/n neutral He atoms observed by the HSTOF/SOHO detector

, 2014
Context. Since 1996, during periods of low solar activity, the HSTOF instrument onboard the SOHO satellite has been measuring weak fluxes of He atoms of 28-58 keV/n (helium energetic neutral atoms - He ENA).

Kinetic Simulation of Magnetic Reconnection with Pickup Ions: Shell Stability and Reconnection Rate Analysis

The Astrophysical Journal
Collisionless magnetic reconnection is postulated to be active in many regions of the heliosphere, where the physics and formation of heliospheric structures are influenced by pickup ions (PUIs).

Bulk etch rate measurements and calibrations of CR39 and Makrofol nuclear track detectors

, 2008
We developed a new method for determining the bulk etch rate velocity based on both cone height and base diameter measurements of the etched tracks. This method is applied here for the calibration of CR39 and Makrofol nuclear track detectors exposed to ...

Hybrid Simulations of Interstellar Pickup Ions at the Solar Wind Termination Shock Revisited

The Astrophysical Journal
We revisit previous hybrid simulations of the heating and acceleration of interstellar pickup ions (PUIs) at the solar wind termination shock. In previous simulations, a relatively cold initial distribution of PUIs was assumed; and while the resulting ...
