Irregular Moons Possibly Injected from the Outer Solar System by a Stellar Flyby

The Astrophysical Journal Letters
The irregular moons orbit the giant planets on distant, inclined, and eccentric trajectories, in sharp contrast with the coplanar and quasicircular orbits of the regular moons.

Long-term Dynamical Stability in the Outer Solar System. II. Detailed Secular Evolution of Four Large Regular and Resonant Trans-Neptunian Objects

The Astronomical Journal
The long-term evolution of the outer solar system is subject to the influence of the giant planets, however, perturbations from other massive bodies located in the region imprint secular signatures, which are discernible in long-term simulations. In this

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 ),

Carbonaceous Chondrite-like Compositions for Proposed Captured Trans-Neptunian Objects Justitia and Pompeja

The Astrophysical Journal Letters
Red spectral slopes (i.e. increasing reflectance with increasing wavelength) and featureless 0.5–2.5 μ m spectra are often associated with the presence of organic material, and there is a sense that the redder the slope, the more organic material is ...

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 ...

Candidate Distant Trans-Neptunian Objects Detected by the New Horizons Subaru TNO Survey

The Planetary Science Journal
We report the detection of 239 trans-Neptunian objects discovered through the ongoing New Horizons survey for distant minor bodies being performed with the Hyper Suprime-Cam mosaic imager on the Subaru Telescope.
