NASA's New Horizons spacecraft flies past Pluto on 14 July 2015, carrying two instruments that detect charged particles. Pluto has a tenuous, extended atmosphere that is escaping the planet's weak gravity. The interaction of the solar wind with Pluto's escaping atmosphere depends on solar wind conditions as well as the vertical structure of Pluto's atmosphere. We have analyzed Voyager 2 particles and fields measurements between 25 and 39 AU and present their statistical variations. We have… Expand
Interplanetary Magnetic Field Sector from Solar Wind around Pluto (SWAP) Measurements of Heavy Ion Pickup near Pluto
On 2015 July 14, the New Horizons spacecraft flew by the Pluto system. The Solar Wind Around Pluto (SWAP) instrument on board New Horizons, which detects ions in the energy per charge range ~0.035 toExpand
Modeling the Solar Wind at the Ulysses, Voyager, and New Horizons Spacecraft
The outer heliosphere is a dynamic region shaped largely by the interaction between the solar wind and the interstellar medium. While interplanetary magnetic field and plasma observations by theExpand
Pluto’s interaction with its space environment: Solar wind, energetic particles, and dust
TLDR
Preliminary results from the two New Horizons instruments that measure charged particles are the Solar Wind Around Pluto (SWAP) instrument and the Pluto Energetic Particle Spectrometer Science Investigation (PEPSSI) instrument are described, which suggest that very few atmospheric molecules are escaping upstream and becoming ionized.

Interstellar Pickup Ion Observations to 38 AU
We provide the first direct observations of interstellar H+ and He+ pickup ions in the solar wind from 22 AU to 38 AU. We use the Vasyliunas and Siscoe model functional form to quantify the pickupExpand
In Situ Observations of Preferential Pickup Ion Heating at an Interplanetary Shock.
TLDR
It is found that H^{+} PUIs, including their suprathermal tail, contain almost half of the total downstream energy flux in the shock frame, suggesting an upstream energetic particle pressure gradient. Expand
Ice giant magnetospheres
TLDR
Continuing to study and explore ice giant magnetospheres is important for comparative planetology as they represent critical benchmarks on a broad spectrum of planetary magnetospheric interactions, and provide insight beyond the scope of the authors' own Solar System with implications for exoplanet Magnetospheres and magnetic reversals.
