Interstellar Pickup Ion Observations to 38 au [PDF]
The Astrophysical Journal Supplement Series, 2017 Abstract We provide the first direct observations of interstellar H+ and He+ pickup ions in the solar wind from 22 to 38 au. We use the Vasyliunas and Siscoe model functional form to quantify the pickup ion distributions, and while the fit parameters generally lie outside their physically expected ranges, this form allows fits that ...

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

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

Heating of the low-latitude solar wind by dissipation of turbulent magnetic fluctuations [PDF]
, 2001 We test a theory presented previously to account for the turbulent transport of magnetic fluctuation energy in the solar wind and the related dissipation and heating of the ambient ion population. This theory accounts for the injection of magnetic energy

Transport of Solar Wind Fluctuations: A Two-Component Model [PDF]
, 2011 We present a new model for the transport of solar wind fluctuations which treats them as two interacting incompressible components: quasi-two-dimensional turbulence and a wave-like piece.

Heating of Pickup and Solar Wind Ions at Jupiter’s Bow Shock [PDF]
, 2004 Interstellar pickup ions are dynamically important in the outer heliosphere where they mass‐load and heat the solar wind. Some of these pickup ions are transformed into energetic neutral atoms (ENAs) by charge exchange with the residual cold interstellar

The acceleration of pickup ions at shock waves: Test particle-mesh simulations [PDF]
, 1998 A mechanism for the acceleration of pickup ions by repeated reflection from the electrostatic cross-shock potential of a quasi-perpendicular shock was proposed independently by Zank et al. [1996b] and Lee et al. [1996].

Solar Control of the Pickup Ion Plume in the Dayside Magnetosheath of Venus
Geophysical 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 Ions beyond the Heliopause
The Astrophysical Journal, 2019 Abstract Fluxes of energetic neutral atoms (ENAs) with energies greater than 1 KeV measured by the Interstellar Boundary Explorer (IBEX) are predominantly created by charge exchange of interstellar neutral atoms with hot, nonthermal (pickup) ions. Since the properties of pickup ions (PUIs) depend on the place of their birth, they bear an
