Zodiacal Fluctuations Should Drive Inner-source Pickup Ion Variability
The Astrophysical JournalDust 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 ...

A hemispherical model of anisotropic interstellar pickup ions [PDF]
Journal of Geophysical Research: Space Physics, 1997 We present an analytical model for the distribution function of interstellar pickup ions in a radially directed heliospheric magnetic field which naturally results in anisotropic particle distributions. The model includes the effects of convection and spatial transport in the solar wind, adiabatic deceleration in the radial flow, adiabatic focusing in ...

Lunar Pickup Ions Observed by ARTEMIS: Spatial and Temporal Distribution and Constraints on Species and Source Locations [PDF]
ARTEMIS observes pickup ions around the Moon, at distances of up to 20,000 km from the surface. The observed ions form a plume with a narrow spatial and angular extent, generally seen in a single energy/angle bin of the ESA instrument. Though ARTEMIS has

Determination of interstellar pickup ion distributions in the solar wind with SOHO and Cluster
Annales GeophysicaeOver the last 10 years, the experimental basis for the study of the local interstellar medium has been substantially enhanced by the direct detection of interstellar pickup ions and of interstellar neutral helium within the heliosphere.

Stability of Adiabatic Processes and Evolution of Pickup Ion Dimensionality
The Astrophysical JournalIn adiabatic processes, such as in many space plasmas, particles flow with no heat entering or exiting their system, while, more generally, the difference between polytropic and adiabatic indices provides a measure of any heating.

The Effects of Turbulence on Heliosheath Ions and Implications for Energetic Neutral Atoms
The Astrophysical JournalThe distribution of ions in the heliosheath—the region between the heliospheric termination shock and the heliopause—is important for understanding remote observations of energetic neutral atoms (ENAs).

Effects of anomalous cosmic rays on the solar wind events in the outer heliosphere
Frontiers in Astronomy and Space SciencesAnomalous cosmic-rays (ACRs) are thought to be originated from the acceleration of pickup ions (PUIs) at the termination shock or interplanetary shocks, and play important role for the plasma dynamics in the outer heliosphere. Due to limited observation,

Nuclear burst plasma injection into the magnetosphere and resulting spacecraft charging [PDF]
, 1977 The passage of debris from a high altitude ( 400 km) nuclear burst over the ionospheric plasma is found to be capable of exciting large amplitude whistler waves which can act to structure a collisionless shock.

PUI Heating in the Supersonic Solar Wind
The Astrophysical JournalThe outer heliosphere is profoundly influenced by nonthermal energetic pickup ions (PUIs), which dominate the internal pressure of the solar wind beyond ~10 au, surpassing both solar wind and magnetic pressures.

Modeling Momentum-Diffusion in the Solar Wind [PDF]
, 2018 The Sun is both a resource and a danger. We must be able to predict or have forewarning of large solar flares and coronal mass ejections (CMEs) and their potential threats to astronauts, GPS, radio communications, and power grids.
