Uranus’s Influence on Neptune’s Exterior Mean-motion Resonances

The Planetary Science Journal
Neptune’s external mean-motion resonances play an important role in sculpting the observed population of trans-Neptunian objects (TNOs). The population of scattering TNOs is known to “stick” to Neptune's resonances while evolving in semimajor axis ( a ),

A Pan-STARRS Search for Distant Planets: Part 1

The Planetary Science Journal
We present a search for distant planets in Pan-STARRS1. We calibrated our search by injecting an isotropic control population of synthetic detections into Pan-STARRS1 source catalogs, providing a high-fidelity alternative to injecting synthetic sources ...

The Effect of Massive Trans-Neptunian Objects in the Long-term Evolution and Leakage Rates of Neptune’s 3:2 and 2:1 Mean Motion Resonances

The Astronomical Journal
The current populations trapped in Neptune’s main mean motion resonances in the Kuiper Belt, Plutinos in the 3:2 and Twotinos in the 2:1, contain some of the best-characterized minor objects in the solar system, given their dynamical importance.

Discovery of a Dwarf Planet Candidate in an Extremely Wide Orbit: 2017 OF201

The Astrophysical Journal Letters
We report the discovery of a dwarf planet candidate, 2017 OF201, currently located at a distance of 90 au. Its orbit is extremely wide and extends to the inner Oort cloud, with a semimajor axis of 830 au and a perihelion of 45 au, precisely determined ...

Taxonomy and densities of Trans-Neptunian objects

, 2010
A Large Programme at ESO has been devoted to the investigation of Centaurs and Trans-Neptunian Objects. In this framework the photometric colors and the light curves of selected targets have been acquired. Here we present and discuss all the results obtained from the photometric technique.

Orbital Characterization of a Newly Discovered Small Satellite around Quaoar

The Astrophysical Journal Letters
Recent observations of a stellar occultation have revealed the presence of a previously undiscovered small satellite around Quaoar. Orbiting near Quaoar’s unusual ring system, this new satellite has the potential to provide significant insights into the ...
