Triaxial shapes and densities of G!kún||'hòmdÃmà , Haumea, and Varda from stellar occultations
Benjamin Proudfoot, Will Grundy, Flavia Luane Rommel +2
The shapes and densities of mid-sized and large trans-Neptunian objects (TNOs) are pivotal for understanding a variety of important aspects of planet formation. In this work, we pr…
Evidence of Possible Spectral Variability in the Patroclus-Menoetius Binary System
Ian Wong, William M. Grundy, Joshua P. Emery +5
We present new visible-wavelength spectroscopic observations of the Patroclus-Menoetius binary system in the Jupiter Trojan population. Motivated by previously published spectra fr…
Orbital Characterization of a Newly Discovered Small Satellite Around Quaoar
Benjamin Proudfoot, Richard Nolthenius, Bryan J. Holler +5
Recent observations of a stellar occultation have revealed the presence of a previously undiscovered small satellite around Quaoar. Orbiting near Quaoar's unusual ring system, this…
Synchronous Rotation in the (120347) Salacia-Actaea System
Cameron Collyer, Estela Fernandez-Valenzuela, Jose Luis Ortiz +8
We report on roughly 16 years of photometric monitoring of the transneptunian binary system (120347) Salacia-Actaea which provides significant evidence that Salacia and Actaea are…
JWST sighting of decameter main-belt asteroids and view on meteorite sources
Artem Y. Burdanov, Julien de Wit, Miroslav Brož +19
Asteroid discoveries are essential for planetary-defense efforts aiming to prevent impacts with Earth, including the more frequent megaton explosions from decameter impactors. Whil…
Observations of Uranus at High Phase Angle as Seen by New Horizons
Samantha N. Hasler, L. C. Mayorga, William M. Grundy +14
We present flux measurements of Uranus observed at phase angles of 43.9°, 44.0°, and 52.4° by the Multispectral Visible Imaging Camera (MVIC) on the New Horizons spacecraft duri…
