OSSOS XX: The Meaning of Kuiper Belt Colors [PDF]

The Astronomical Journal, 2020
Abstract Observations show that 100 km class Kuiper Belt objects (KBOs) can be divided into (at least) two color groups, red (R; g − i < 1.2) and very red (VR; g − i > 1.2), reflecting a difference in their surface composition. This is thought to imply that KBOs formed over a relatively wide range of radial distance, r.

OSSOS. XIX. Testing Early Solar System Dynamical Models Using OSSOS Centaur Detections [PDF]

The Astronomical Journal, 2019
Abstract We use published models of the early solar system evolution with a slow, long-range and grainy migration of Neptune to predict the orbital element distributions and the number of modern-day Centaurs. The model distributions are biased by the Outer Solar System Origins Survey (OSSOS) simulator and compared with the OSSOS Centaur ...

OSSOS. XIV. The Plane of the Kuiper Belt [PDF]

The Astronomical Journal, 2019
Abstract The orbits of solar system objects are subject to perturbations by other massive bodies and slowly precess about a forced (averaged) plane. Warps in the plane come from the effects of the total planetary system, so discrepancies from expectation can show the presence of any unseen planets.

Col-OSSOS: The Colours of the Outer Solar System Origins Survey [PDF]

Astrophysical Journal Supplement Series, 2019
The Colours of the Outer Solar System Origins Survey (Col-OSSOS) is acquiring near-simultaneous $g$, $r$, and $J$ photometry of unprecedented precision with the Gemini North Telescope, targeting nearly a hundred trans-Neptunian objects (TNOs) brighter ...

OSSOS III - RESONANT TRANS-NEPTUNIAN POPULATIONS: CONSTRAINTS from the FIRST QUARTER of the OUTER SOLAR SYSTEM ORIGINS SURVEY [PDF]

, 2016
The first two observational sky "blocks" of the Outer Solar System Origins Survey (OSSOS) have significantly increased the number of well characterized observed trans-Neptunian objects (TNOs) in Neptune's mean motion resonances.

OSSOS. IX. Two Objects in Neptune's 9: 1 Resonance - Implications for Resonance Sticking in the Scattering Population [PDF]

Astronomical Journal, 2018
We discuss the detection in the Outer Solar System Origins Survey (OSSOS) of two objects in Neptune's distant 9:1 mean motion resonance at semimajor axis $a\approx~130$~au. Both objects are securely resonant on 10~Myr timescales, with one securely in the

OSSOS. IV. DISCOVERY OF A DWARF PLANET CANDIDATE IN THE 9 : 2 RESONANCE WITH NEPTUNE [PDF]

, 2016
We report the discovery and orbit of a new dwarf planet candidate, 2015 RR245, by the Outer Solar System Origins Survey (OSSOS). The orbit of 2015 RR245 is eccentric (e = 0.586), with a semimajor axis near 82 au, yielding a perihelion distance of 34 au ...

OSSOS. XXIX. The Population and Perihelion Distribution of the Detached Kuiper Belt [PDF]

The Planetary Science Journal, 2023
The detached trans-Neptunian objects (TNOs) are those with semimajor axes beyond the 2:1 resonance with Neptune that are neither resonant nor scattering.

OSSOS XXV: Large Populations and Scattering–Sticking in the Distant Trans-Neptunian Resonances [PDF]

The Planetary Science Journal, 2022
There have been 77 TNOs discovered to be librating in the distant trans-Neptunian resonances (beyond the 2:1 resonance, at semimajor axes greater than 47.7 au) in four well-characterized surveys: the Outer Solar System Origins Survey (OSSOS) and three ...
