Weywot, an Unusually Low-albedo Satellite in the Trans-Neptunian Region

The Astrophysical Journal Letters
Weywot is the largest satellite of the candidate dwarf planet Quaoar, which also hosts a remarkable ring system located beyond its Roche limit—a configuration that challenges conventional understanding of ring dynamics.

Measuring Apsidal Clustering

The Astrophysical Journal
The decade-long debate over the existence of apsidal clustering in the outer solar system is poised for reignition given the plethora of distant trans-Neptunian object (TNO) discoveries expected from the forthcoming Vera C.

A Near-infrared Survey of Candidate Haumea Family Members

The Astronomical Journal
The Haumea family is the only known dynamical family in the trans-Neptunian region. To date, 10 family members have been unambiguously identified using near-infrared (NIR) spectral or photometric data in combination with their strong dynamical proximity ...

The Inner Kernel of the Classical Kuiper Belt

The Astrophysical Journal Letters
The “kernel” of the classical Kuiper Belt was discovered by Petit et al. as a visual overdensity of objects with low ecliptic inclinations and eccentricities at semimajor axes near ∼44 au.

Early Stellar Flybys are Unlikely: Improved Constraints from Sednoids and Large-q Trans-Neptunian Objects

The Astrophysical Journal
Sedna-like objects (a.k.a. sednoids) are trans-Neptunian objects (TNOs) characterized by large semimajor axes and exceptionally high perihelia. Their high- q orbits are detached from the influence of the four giant planets and need extra perturbation to ...

The Surfaces of Small to Midsize Plutinos: Evidence of an Association between Inclination and Surface Type

The Planetary Science Journal
Being one of the most populated mean motion resonances (MMRs) with Neptune and lying close to the inner boundary of the present-day cold classical disk, observations of the orbital and surface class distributions of the plutinos in the 3:2 MMR provide ...
