Formation and Migration of Trans-Neptunian Objects [PDF]

AIP Conference Proceedings, 2004
Trans-Neptunian objects (TNOs) with diameter d>100 km moving now in not very eccentric orbits could be formed directly by the compression of large rarefied dust condensations (with semi-major axes a>30 AU), but not by the accretion of smaller solid planetesimals.

Advanced Techniques in Stability Analysis of Trans-Neptunian Objects

Universe
The trans-Neptunian region (30–50 AU) is a dynamically structured reservoir of icy planetesimals whose orbital architecture reflects resonant dynamics, chaotic transport, and long-term gravitational sculpting by the giant planets. This review synthesizes

A Spiral Structure in the Inner Oort Cloud

The Astrophysical Journal
As the Galactic tide acts to decouple bodies from the scattered disk it creates a spiral structure in physical space that is roughly 15,000 au in length. The spiral is long-lived and persists in the inner Oort cloud to the present time.

Photometry of Outer Solar System Objects from the Dark Energy Survey. I. Photometric Methods, Light-curve Distributions, and Trans-Neptunian Binaries

The Astrophysical Journal Supplement Series, 2023
We report the methods of and initial scientific inferences from the extraction of precision photometric information for the >800 trans-Neptunian objects (TNOs) discovered in the images of the Dark Energy Survey (DES). Scene-modeling photometry is used to

Water‐Ice Dominated Spectra of Saturn's Rings and Small Moons From JWST

Journal of Geophysical Research: Planets, Volume 129, Issue 3, March 2024.
Abstract JWST measured the infrared spectra of Saturn's rings and several of its small moons (Epimetheus, Pandora, Telesto, and Pallene) as part of Guaranteed Time Observation program 1247. The NIRSpec instrument obtained near‐infrared spectra of the small moons between 0.6 and 5.3 microns, which are all dominated by water‐ice absorption bands.

OSSOS. VII. 800+ Trans-Neptunian Objects—The Complete Data Release [PDF]

, 2018
The Outer Solar System Origins Survey (OSSOS), a wide-field imaging program in 2013–2017 with the Canada–France–Hawaii Telescope, surveyed 155 deg2 of sky to depths of m r = 24.1–25.2.

THE INCLINATIONS OF FAINT TRANS-NEPTUNIAN OBJECTS

The Astrophysical Journal, 2010
Bernstein et al. found that the population of faint (R> 26) trans-Neptunian objects (TNOs) known at that time was dominated by "Classical" objects, which have low inclinations (i < 5°) and distances of 40-45 AU. Since those observations, the number of faint TNOs whose orbits are sufficiently well known to be classified as "Classical" or "Excited" has ...
