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…
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…
An Extremely Deep Rubin Survey to Explore the Extended Kuiper Belt and Identify Objects Observable by New Horizons
JJ Kavelaars, Marc W. Buie, Wesley C. Fraser +22
A proposed Vera C. Rubin Observatory Deep Drilling micro-survey of the Kuiper Belt will investigate key properties of the distant solar system. Utilizing 30 hours of Rubin time acr…
Ejecta Evolution Following a Planned Impact into an Asteroid: The First Five Weeks
Theodore Kareta, Cristina Thomas, Jian-Yang Li +85
The impact of the DART spacecraft into Dimorphos, moon of the asteroid Didymos, changed Dimorphos' orbit substantially, largely from the ejection of material. We present results fr…
The hot main Kuiper belt size distribution from OSSOS
Jean-Marc Petit, Brett Gladman, J. J. Kavelaars +4
Using the absolute detection calibration and abundant detections of the OSSOS (Outer Solar System Origin Survey) project, we provide population measurements for the main Kuiper Bel…
The Galactic Interstellar Object Population: A Framework for Prediction and Inference
Matthew J. Hopkins, Chris Lintott, Michele T. Bannister +2
The Milky Way is thought to host a huge population of interstellar objects (ISOs), numbering approximately around the Sun, which are formed and shaped by…
OSSOS. XXIX. The Population and Perihelion Distribution of the Detached Kuiper Belt
Matthew Beaudoin, Brett Gladman, Yukun Huang +4
The detached transneptunian objects (TNOs) are those with semimajor axes beyond the 2:1 resonance with Neptune, which are neither resonant nor scattering. Using the detached sample…
OSSOS: XXVII. Population Estimates for Theoretically Stable Centaurs Between Uranus and Neptune
Rosemary C. Dorsey, Michele T. Bannister, Samantha M. Lawler +1
We calculate the upper bounds of the population of theoretically stable Centaur orbits between Uranus and Neptune. These small bodies are on low-eccentricity, low-inclination orbit…
Tuning the Legacy Survey of Space and Time (LSST) Observing Strategy for Solar System Science
Megan E. Schwamb, R. Lynne Jones, Peter Yoachim +27
The Vera C. Rubin Observatory is expected to start the Legacy Survey of Space and Time (LSST) in early to mid-2025. This multi-band wide-field synoptic survey will transform our vi…
Ejecta from the DART-produced active asteroid Dimorphos
Jian-Yang Li, Masatoshi Hirabayashi, Tony L. Farnham +61
Some active asteroids have been proposed to be the result of impact events. Because active asteroids are generally discovered serendipitously only after their tail formation, the p…
The LCO Outbursting Objects Key Project: Overview and Year 1 Status
Tim Lister, Michael S. P. Kelley, Carrie E. Holt +32
The LCO Outbursting Objects Key (LOOK) Project uses the telescopes of the Las Cumbres Observatory (LCO) Network to: (1) to systematically monitor a sample of Dynamically New Comets…
Col-OSSOS: Evidence for a compositional gradient inherited from the protoplanetary disk?
Michael Marsset, Wesley C. Fraser, Megan E. Schwamb +7
In the present-day Kuiper Belt, the number of compositional classes and the orbital distributions of these classes hold important cosmogonic implications for the Solar System. In a…
Col-OSSOS: The Two Types of Kuiper Belt Surfaces
Wesley C. Fraser, Rosemary E. Pike Michael Marsset, Megan E. Schwamb +10
The Colours of the Outer Solar System Origins Survey (Col-OSSOS) has gathered high quality, near-simultaneous (g-r) and (r-J) colours of 92 Kuiper Belt Objects (KBOs) with (u-g) an…
Col-OSSOS: The Distribution of Surface Classes in Neptune's Resonances
Rosemary E. Pike, Wesley C. Fraser, Kathryn Volk +9
The distribution of surface classes of resonant trans-Neptunian objects (TNOs) provides constraints on the protoplanetesimal disk and giant planet migration. To better understand t…
OSSOS XXV: Large Populations and Scattering-Sticking in the Distant Transneptunian Resonances
B. L. Crompvoets, S. M. Lawler, K. Volk +8
There have been 77 TNOs discovered to be librating in the distant transneptunian resonances (beyond the 2:1 resonance, at semimajor axes greater than 47.7~AU) in four well-characte…
Col-OSSOS: Probing Ice Line/Color Transitions within the Kuiper Belt's Progenitor Populations
Laura E. Buchanan, Megan E. Schwamb, Wesley C. Fraser +15
Dynamically excited objects within the Kuiper belt show a bimodal distribution in their surface colors, and these differing surface colors may be a tracer of where these objects fo…
OSSOS. XXIII. 2013 VZ70 and the Temporary Coorbitals of the Giant Planet
Mike Alexandersen, Sarah Greenstreet, Brett J. Gladman +8
We present the discovery of 2013 VZ70, the first known horseshoe coorbital companion of Saturn. Observed by the Outer Solar System Origins Survey (OSSOS) for 4.5 years, the orbit o…
OSSOS finds an Exponential Cutoff in the Size Distribution of the Cold Classical Kuiper belt
JJ Kavelaars, Jean-Marc Petit, Brett Gladman +5
The cold main classical Kuiper Belt consists of those non-resonant small solar system bodies with low orbital inclinations and orbital semi-major axes between 42.4 and 47.7 au. The…
