A transient enhancement of Mercury’s exosphere at extremely high altitudes inferred from pickup ions [PDF]

open access: yesNature Communications, 2020
Mercury has a global dayside exosphere that is very tenuous and does not extend far from the planet. Here, the authors show enhancement of neutral densities at high altitudes inferred from pickup ions that is most likely caused by the impact of a ...

The temporal and latitudinal dependences of turbulence driven by pickup ions in the outer heliosphere

open access: yesFrontiers in Astronomy and Space Sciences, 2023
The distribution of turbulence in the heliosphere remains a mystery, due to the complexity in not only modeling the turbulence transport equations but also identifying the drivers of turbulence that vary with time and spatial location.

The Impact of Pickup Ion Thermal Spread on Pickup Ion Ring-beam-driven Instabilities and Scattering in the Outer Heliosheath

open access: yesThe Astrophysical Journal, 2023
The present study investigates the unstable waves driven by the pickup ions of ring-beam distributions with various pickup angles and pickup ion temperatures in the outer heliosheath, using both linear instability analysis and hybrid simulations.

Determination of interstellar pickup ion distributions in the solar wind with SOHO and Cluster [PDF]

open access: yesAnnales Geophysicae, 1996
Over 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.

Toward Interpreting the IBEX Ribbon with Mirror Diffusion in Interstellar Turbulent Magnetic Fields

open access: yesThe Astrophysical Journal, 2023
We investigate the role of the magnetohydrodynamic (MHD) turbulence measured by Voyager in the very local interstellar medium (VLISM) in modeling the Interstellar Boundary Explorer ribbon.

Bulk Properties of Pickup Ions Derived from the Ulysses Solar Wind Ion Composition Spectrometer Data

open access: yesThe Astrophysical Journal, 2022
Nonthermal, pickup ions (PUIs) represent an energetic component of the solar wind (SW). While a number of theoretical models have been proposed to describe the PUI flow, of major importance are in situ measurements providing us with the vital source of ...

Solar Control of the Pickup Ion Plume in the Dayside Magnetosheath of Venus

open access: yesGeophysical Research Letters, 2023
Using the 8.5‐year Venus Express measurements, we demonstrate the asymmetric plasma distributions in the Venusian magnetosheath. An escaping plume is formed by pickup oxygen ions in the hemisphere where the motional electric field points outward from ...

Pickup Ion–Mediated Magnetic Reconnection in the Outer Heliosphere

open access: yesThe Astrophysical Journal Letters, 2023
Pickup ions (PUIs) play a crucial role in the heliosphere, contributing to the mediation of large-scale structures such as the distant solar wind, the heliospheric termination shock, and the heliopause.
