Observations of the helium focusing cone with pickup ions [PDF]

, 2004
The helium gravitational focusing cone has been observed using pickup He+, first during the solar minimum in 1984–1985 with the AMPTE/IRM spacecraft, and again in more detail from 1998 to 2002 with ACE and in 2000 with Nozomi. Five traversals of the cone

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.

Direct Acceleration of Pickup Ions at The Solar Wind Termination Shock: The Production of Anomalous Cosmic Rays [PDF]

, 1998
We have modeled the injection and acceleration of pickup ions at the solar wind termination shock and investigated the parameters needed to produce the observed Anomalous Cosmic Ray (ACR) fluxes.

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).

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 ...

Low-frequency Waves due to Newborn Interstellar Pickup He+ Observed by the Ulysses Spacecraft [PDF]

, 2022
We have surveyed magnetic field data from the Ulysses spacecraft and found examples of magnetic waves with the expected characteristics that point to excitation by newborn pickup He+.

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 ...

Two years of solar wind and pickup ion measurements at comet 67P/Churyumov–Gerasimenko [PDF]

, 2017
The Ion and Electron Sensor (IES) as well as other members of the Rosetta Plasma Consortium (RPC) on board the Rosetta spacecraft (S/C) measured the characteristics of the solar wind almost continuously since its arrival at 67P/Churyumov–Gerasimenko (CG)

Zodiacal Fluctuations Should Drive Inner-source Pickup Ion Variability

The Astrophysical Journal
Dust near the Sun is implicated in the production of an unexpected “inner source” of pickup ions (PUIs). Multiple mechanisms related to dust have been proposed to explain this phenomenon, and all depend on the amount, along with the spatial and size ...
