LiDO: The Large inclination Distant Objects Survey
Mike Alexandersen, Rosemary E. Pike, Ying-Tung Chen +20
Previous trans-Neptunian objects (TNOs) discovery surveys targeted the ecliptic plane, where the overall highest density is seen. High-inclination objects spend little time near th…
The Dense, Rocky Core of Haumea Revealed by Satellite Dynamics
Benjamin Proudfoot, Darin Ragozzine, Will Grundy +2
The icy dwarf planets in the outer solar system are among the most enigmatic bodies known, showing activity ranging from atmospheric resurfacing to possible cryovolcanism. Yet the…
Beyond Point Masses. VI. Spin-Orbit Evolution of the Centaur Binary Typhon-Echidna
Benjamin Proudfoot, Will Grundy, Darin Ragozzine
Only three binaries have been identified among the Centaur population. Because their perihelia are significantly closer than those of other trans-Neptunian binaries (TNBs), these s…
Kilometre-scale Jovian moon characterized for a potential JUICE flyby
Juan Luis Rizos, Jose Maria Gomez-Limon, Yucel Kilic +51
Jupiter's irregular satellites are thought to be relics of early Solar System planetesimals. However, their small sizes, large distances from Earth and close angular proximity to J…
Rotation and Mutual Eclipse Events Season in the Kuiper Belt: (524366) 2001 XR
Audrey Thirouin, William M. Grundy, Scott S. Sheppard +3
(524366) 2001 XR is a dynamically Cold Classical Kuiper Belt Object that is a nearly equal-sized wide binary whose upcoming mutual events season makes it a particularly val…
Triaxial shapes and densities of G!kún||'hòmdímà, 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…
Trans-Neptunian Binary Mutual Events in the 2020s and 2030s
Benjamin Proudfoot, Will Grundy, Darin Ragozzine
Mutual events of trans-Neptunian binaries (TNBs) provide rare opportunities to measure the physical and orbital properties of small bodies in the outer solar system. However, succe…
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…
Beyond Point Masses. V. Weywot's Non-Keplerian Orbit
Benjamin Proudfoot, Will Grundy, Darin Ragozzine +1
We present a detailed dynamical analysis of the Quaoar-Weywot system based on nearly 20 years of high-precision astrometric data, including new HST observations and stellar occulta…
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…
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…
Prediction and observation of a stellar occultation by Haumea's satellite Namaka
F. L. Rommel, B. C. N. Proudfoot, B. J. Holler +2
Stellar occultations are an ideal way to characterize the physical and orbital properties of trans-Neptunian binary systems. In this research note, we detail the prediction and obs…
Stellar occultation observations of (38628) Huya and its satellite: a detailed look into the system
F. L. Rommel, E. Fernández-Valenzuela, B. C. N. Proudfoot +78
The physical and orbital parameters of Trans-Neptunian Objects (TNOs) provide valuable information about the Solar System's formation and evolution. In particular, the characteriza…
Beyond Point Masses. IV. TNO Altjira is Likely a Hierarchical Triple Discovered Through Non-Keplerian Motion
Maia A Nelsen, Darin Ragozzine, Benjamin C. N. Proudfoot +2
Dynamically studying Trans-Neptunian Object (TNO) binaries allows us to measure masses and orbits. Most of the known objects appear to have only two components, except (47171) Lemp…
Beyond Point Masses. I. New Non-Keplerian Modeling Tools Applied to Trans-Neptunian Triple (47171) Lempo
Darin Ragozzine, Seth Pincock, Benjamin C. N. Proudfoot +3
Many details of the formation and evolution of the solar system are best inferred by understanding the orbital and physical properties of small bodies in the solar system. For exam…
Beyond Point Masses. II. Non-Keplerian Shape Effects are Detectable in Several TNO Binaries
Benjamin C. N. Proudfoot, Darin A. Ragozzine, Meagan L. Thatcher +60
About 40 transneptunian binaries (TNBs) have fully determined orbits with about 10 others being solved except for breaking the mirror ambiguity. Despite decades of study almost all…

Benjamin C. N. Proudfoot, Darin A. Ragozzine, William Giforos +3
The dwarf planet Haumea is one of the most compelling transneptunian objects (TNOs) to study, hosting two small, dynamically interacting satellites, a family of nearby spectrally u…
The formation of Haumea and its family via binary merging
Benjamin Proudfoot, Darin Ragozzine
Dozens of families of asteroids in the asteroid belt have similar orbits and compositions because they formed through a collision. However, the icy debris beyond the orbit of Neptu…
A Dearth of Small Members in the Haumea Family Revealed by the OSSOS Survey
