Perspectives on the distribution of orbits of distant Trans-Neptunian objects [PDF]

, 2020
Looking at the orbits of small bodies with large semimajor axes, we are compelled to see patterns. Some of these patterns are noted as strong indicators of new or hidden processes in the outer Solar System, others are substantially generated by observational biases, and still others may be completely overlooked. We can gain insight into the current and

Maximum Likelihood Systematic Effect Modeling and Matched Filtering to Detect Trans-Neptunian Objects with TESS

, 2022
We present a pipeline for searching for trans-Neptunian objects (TNOs) using data from the TESS mission, that includes a novel optimization-based framework for subtracting the effects of scattered light and pointing jitter.

The Properties and Origin of Kuiper Belt Object Arrokoth's Large Mounds

The Planetary Science Journal, 2023
We report on a study of the mounds that dominate the appearance of Kuiper Belt Object (486958) Arrokoth's larger lobe, named Wenu. We compare the geological context of these mounds and measure and intercompare their shapes, sizes/orientations ...

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.

Beyond Point Masses. IV. Trans-Neptunian Object Altjira Is Likely a Hierarchical Triple Discovered through Non-Keplerian Motion

The Planetary Science Journal
Dynamically studying trans-Neptunian object (TNO) binaries allows us to measure masses and orbits. Most of the known objects appear to have only two components, except (47171) Lempo, which is the single known hierarchical triple system with three similar-

Misaligned Rings Around Minor Planets with Moons

Universe
Recent observations have confirmed the existence of rings around minor bodies in the outer solar system. These objects may possess satellites as well. Here, we analytically investigate the interaction between such rings and satellites.

The DECam Ecliptic Exploration Project (DEEP). III. Survey Characterization and Simulation Methods

The Astronomical Journal
We present a detailed study of the observational biases of the DECam Ecliptic Exploration Project’s B1 data release and survey simulation software that enables direct statistical comparisons between models and our data.

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 ...
