What Observations Would an Energetic Neutral Atom Imager Have Made During the Voyager 2 Flyby of Uranus?

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We present large‐scale simulations of energetic neutral atom (ENA) emissions at Uranus from a spacecraft viewpoint. Models of magnetic field, extended hydrogen exosphere, moon‐sourced neutral tori, and proton radiation belt are implemented into a simulator to evaluate the production of ENAs for L $L$ = 1–15.

Designing Trajectories to Uranus Using Particle Swarm Optimization

open access: yes, 2023
As the interest in interplanetary missions becomes more prevalent in the modern day, two planets have been infrequently visited, Uranus and Neptune. Yet, the 2013-2022 and 2023-2032 Decadal Surveys have placed high priority on Uranus missions.

Skepticism and Ontological Parsimony

open access: yesPacific Philosophical Quarterly, Volume 107, Issue 2, Page 86-98, June 2026.
ABSTRACT External world skepticism is often thought to entail that we should suspend judgment about the existence of the external world. I challenge this orthodoxy by arguing that, when combined with a plausible principle of ontological parsimony, the skeptical challenge intensifies into an argument for outright disbelief in the external world.

The Upper Atmosphere of Uranus from Stellar Occultations. II. Revised Temperatures in the Upper Stratosphere and Lower Thermosphere

open access: yesThe Planetary Science Journal
Measurements made by Voyager 2 during its flyby of Uranus in 1986 found warm stratospheric and hot thermospheric temperatures that cannot be explained by solar energy alone.

(Co‐)Reference All the Way Down: A Unified Theory of (Pro) Nominals in Ordinary English

open access: yesTheoria, Volume 92, Issue 3, June 2026.
ABSTRACT This essay joins two themes, both arising from Kripke's inspiring ideas in the theory of reference. The first theme concerns reference in general. The second examines the notion of co‐reference and the role it plays in a unified theory of pronouns for natural language.

Uranus, Neptune, and Exoplanets

open access: yes, 2013
This chapter focuses on the climates of Uranus, Neptune, and exoplanets. Uranus spins on its side, which allows a comparison between sunlight and rotation for their effects on weather patterns. In contrast to Venus, Uranus is only weakly affcted by tides

Reassessing planetary composition: Evidence of rock-dominated envelopes in Uranus and Neptune

open access: yesAstronomy & Astrophysics
Although Uranus and Neptune are commonly classified as ice giants, their exact compositions remain poorly constrained. Recent studies of outer Solar System bodies challenge the traditional view that these planets are primarily ice-dominated, suggesting ...
