TL;DR
The OSSOS survey discovered over 800 trans-Neptunian objects with highly accurate orbits, significantly expanding the known populations and providing detailed data crucial for understanding Neptune's migration and the Solar System's outer structure.
Contribution
This paper presents the complete data release of OSSOS, including 838 TNOs with precise orbits, doubling the known non-resonant Kuiper belt population and greatly enhancing the sample of resonant objects.
Findings
Increased the known TNO population by nearly 50%.
Identified new resonant populations and orbital features.
Provided a detailed survey bias model for statistical analyses.
Abstract
The Outer Solar System Origins Survey (OSSOS), a wide-field imaging program in 2013-2017 with the Canada-France-Hawaii Telescope, surveyed 155 deg of sky to depths of -25.2. We present 838 outer Solar System discoveries that are entirely free of ephemeris bias. This increases the inventory of trans-Neptunian objects (TNOs) with accurately known orbits by nearly 50%. Each minor planet has 20-60 Gaia/Pan-STARRS-calibrated astrometric measurements made over 2-5 oppositions, which allows accurate classification of their orbits within the trans-Neptunian dynamical populations. The populations orbiting in mean-motion resonance with Neptune are key to understanding Neptune's early migration. Our 313 resonant TNOs, including 132 plutinos, triple the available characterized sample and include new occupancy of distant resonances out to semi-major axis au. OSSOS…
