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…
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…
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…
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…
Beyond Point Masses. III. Detecting Haumea's Nonspherical Gravitational Field
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 Equilibrium Vapor Pressures of Ammonia and Oxygen Ices at Outer Solar System Temperatures
B. P. Blakley, Will M. Grundy, Jordan K. Steckloff +8
Few laboratory studies have investigated the vapor pressures of the volatiles that may be present as ices in the outer solar system; even fewer studies have investigated these spec…
Laboratory Measurement of Volatile Ice Vapor Pressures with a Quartz Crystal Microbalance
W. M. Grundy, S. C. Tegler, J. K. Steckloff +12
Nitrogen, carbon monoxide, and methane are key materials in the far outer Solar System where their high volatility enables them to sublimate, potentially driving activity at very l…
OSS (Outer Solar System): A fundamental and planetary physics mission to Neptune, Triton and the Kuiper Belt
Bruno Christophe, Linda J. Spilker, John D. Anderson +46
The present OSS mission continues a long and bright tradition by associating the communities of fundamental physics and planetary sciences in a single mission with ambitious goals…
