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…

LiDO: Discovery of a 10:1 Resonator with a Novel Libration State

Rosemary E. Pike, Ruth Murray-Clay, Kathryn Volk +9

The Large inclination Distant Objects LiDO survey has discovered the first securely classified object in the 10:1 mean motion resonance of Neptune. This object, 2020 VN40, is short…

The Surfaces of Small to Mid-Size Plutinos: Evidence of an Association Between Inclination and Surface Type

Cameron Collyer, Rosemary E. Pike, Ying-Tung Chen +6

Being one of the most populated mean motion resonances (MMR) with Neptune and lying close to the inner boundary of the present day cold classical disk, observations of the orbital…

Constraints on Quaoar's rings and atmosphere from JWST/NIRCam observations of a stellar occultation

Benjamin Proudfoot, Bryan Holler, Ko Arimatsu +3

Observations of stellar occultations have revealed that small bodies are capable of hosting ring systems. The trans-Neptunian object (TNO) Quaoar, is the host of an enigmatic ring…

LiDO: Exploring the Stable Plutino Parameter Space

Samantha M. Lawler, Mark Comte, Rosemary E. Pike +7

We present a publicly available, high-resolution, filled-parameter-space synthetic distribution of the Plutinos, trans-Neptunian Objects (TNOs) librating in the 3:2 mean-motion res…
