Col-OSSOS: Investigating the Origins of Different Surfaces in the Primordial Kuiper Belt

Laura E. Buchanan, Megan E. Schwamb, Wesley C. Fraser +12

The Colours of the Outer Solar System Origins Survey (Col-OSSOS) measured the optical/NIR colours of a brightness-complete sample of Trans-Neptunian Objects (TNOs). Like previous s…

Retrograde predominance of small saturnian moons reiterates a recent retrograde collisional disruption

Edward Ashton, Brett Gladman, Mike Alexandersen +1

We report the discovery and careful orbital determination of 64 new irregular moons of Saturn found in images taken using the Canada-France-Hawaii Telescope from 2019-2021, bringin…

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…

Discovery and dynamics of a Sedna-like object with a perihelion of 66 au

Ying-Tung Chen, Patryk Sofia Lykawka, Yukun Huang +30

Trans-Neptunian objects (TNOs) with large perihelion distances ( au) and semi-major axes ( au) provide insights into the early evolution of the solar system and th…

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…

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…
