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 ...

Nitrogen-bearing Species on Trans-Neptunian Objects Revealed by JWST/DiSCo-TNOs

The Astrophysical Journal
C≡N-bearing species are valuable tracers of nitrogen chemistry in the solar system. Ranging from volatile compounds like HCN and CH _3 CN in cometary comae to refractory CN-bearing organics in some micrometeorites and interplanetary dust particles, these

Can Neptune’s Distant Mean Motion Resonances Constrain Undiscovered Planets in the Solar System? Lessons from a Case Study of the 9:1 Resonance

The Planetary Science Journal
Recent observational surveys of the outer solar system provide evidence that Neptune's distant n :1 mean motion resonances may harbor relatively large reservoirs of trans-Neptunian objects (TNOs). In particular, the discovery of two securely classified 9:
