We present a method to identify distant solar system objects in long-term wide-field asteroid survey data, and conduct a search for them in the Pan-STARRS1 (PS1) image data acquired from 2010 to mid-2015. We demonstrate that our method is able to find multi-opposition orbital links, and we present the resulting orbital distributions which consist of 154 Centaurs, 255 classical Trans-Neptunian Objects (TNOs), 121 resonant TNOs, 89 Scattered Disc Objects (SDOs) and 10 comets. Our results show more than half of these are new discoveries, including a newly discovered 19th magnitude TNO. Our identified objects do not show clustering in their argument of perihelia, which if present, might support the existence of a large unknown planetary-sized object in the outer solar system.

  1. Predictions of the LSST Solar System Yield: Discovery Rates and Characterizations of Centaurs

    astro-ph.EP 2025-06 conditional novelty 6.0 of 10

    Using a detailed survey simulator, the authors predict the LSST will discover roughly 1,200 to 2,000 Centaurs over ten years, about half in the first two years.

  2. From Planetesimals to Dwarf Planets by Pebble Accretion

    astro-ph.EP 2025-02 conditional novelty 6.0 of 10

    Pebble accretion in a primordial ring can explain why the hot Kuiper belt holds more dwarf planets than the cold belt, and points to pebbles with Stokes number about 0.01 in mildly turbulent gas.

  3. A Pan-STARRS Search for Distant Planets: Part 1

    astro-ph.EP 2025-06 conditional novelty 5.0 of 10

    A catalog-level injection calibration of Pan-STARRS1 recovers 692 Kuiper Belt objects and constrains Planet Nine's remaining sky area to the galactic plane.

  4. Multi-year Ground-Based Survey Photometry of Active Comet 103P/Hartley 2 and Centaur (2060) Chiron: A Tale of Two Comets in the Pre-LSST Era

    astro-ph.EP 2026-06 unverdicted novelty 4.0 of 10

    Reports asymmetric heliocentric activity slopes for 103P/Hartley 2 and exponential outburst decay plus flattening phase curves for Chiron from ATLAS, ZTF, and LCO photometry.
