Interstellar Pickup Ion Observations to 60 au
The Astrophysical JournalAbstract Prior to the Solar Wind Around Pluto (SWAP) observations from New Horizons, the only significant interstellar pickup ion (PUI) observations were taken inside 5.4 au from the Ulysses and 1 au missions. Here, we analyze SWAP data to provide the first comprehensive radial profile of interstellar PUIs in the outer heliosphere from ...

Pickup Ion Production and Turbulence in the Global Heliosphere
The Astrophysical JournalThe outer heliosphere model in the Space Weather Modeling Framework describes the dynamics of the thermal solar wind, pickup ions, electrons, and neutrals. We have extended this model with turbulence transport and a kinetic description of the pickup ions

Radial evolution of cross helicity at low and high latitudes in the solar wind [PDF]
, 2005 We employ a turbulence transport theory to the radial evolution of the solar wind at both low and high latitudes. The theory includes cross helicity, magnetohydrodynamic (MHD) turbulence, and driving by shear and pickup ions. The radial decrease of cross

A Reduced Chi Squared Analysis of Pickup Ions in the Plasma Field about Europa [PDF]
Jupiter’s magnetosphere hosts large plasma fields that weather the surface of Europa during its transit, freeing neutral molecules into the atmosphere. As these molecules travel into the ionosphere, they are ionized by the plasma field and picked up by

Solar Orbiter’s Passage through Comet Leonard’s Tail while in the He+ Focusing Cone
The Astrophysical JournalThe Solar Orbiter spacecraft crossed Comet Leonard’s ion tail on 2021 December 17 near 1 au. In and near the ion tail, significant amounts of singly charged oxygen (O ^+ ) ions were detected by the Heavy Ion Sensor on board the spacecraft. These ions are
