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

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.

Generation of Low-inclination, Neptune-crossing Trans-Neptunian Objects by Planet Nine

The Astrophysical Journal Letters
The solar system’s distant reaches exhibit a wealth of anomalous dynamical structure, hinting at the presence of a yet-undetected, massive trans-Neptunian body—Planet Nine (P9).

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 ...

Spectroscopic Study of Ice Analogs of Trans-Neptunian Objects Exposed to Ionizing Radiation. II. Infrared Spectra and Functional Groups

The Astrophysical Journal Supplement Series
The surfaces of airless trans-Neptunian objects (TNOs) are subject to continuous ionizing radiation from solar winds and Galactic cosmic rays accompanied by alteration of surface compositions.

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

Spectral Characterization of the Organic- and Methanol-rich Cliff-type Trans-Neptunian Objects

The Astronomical Journal
Trans-Neptunian objects (TNOs) harbor pristine materials from the early solar system. The James Webb Space Telescope offers major insights into the spectral classification of these small bodies.

Machine Learning Assisted Dynamical Classification of Trans-Neptunian Objects

arXiv.org
Trans-Neptunian objects (TNOs) are small, icy bodies in the outer solar system. They are observed to have a complex orbital distribution that was shaped by the early dynamical history and migration of the giant planets.

Radial distribution of distant trans-Neptunian objects points to Sun’s formation in a stellar cluster [PDF]

Icarus (New York, N.Y. 1962), 2023
The Scattered Disk Objects (SDOs) are a population of trans-Neptunian bodies with semimajor axes $5035$~au) are of special interest here as an important constraint on the early evolution of the outer Solar System.

Free Inclinations for Trans-Neptunian Objects in the Main Kuiper Belt [PDF]

Astrophysical Journal Supplement Series, 2022
There is a complex inclination structure present in the trans-Neptunian object (TNO) orbital distribution in the main classical-belt region (between orbital semimajor axes of 39 and 48 au).

Col-OSSOS: The Distribution of Surface Classes in Neptune's Resonances

The Planetary Science Journal, 2023
The distribution of surface classes of resonant trans-Neptunian objects (TNOs) provides constraints on the protoplanetesimal disk and giant planet migration.
