Hunting for Hydrated Minerals on Trans-Neptunian Objects

The Planetary Science Journal
We present new optical reflectance spectra of three potentially silicate-rich trans-Neptunian objects (TNOs). These spectra were obtained with the aim of confirming past hints and detections of λ ∼ 0.7 μ m absorption features associated with the presence

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

The Astrophysical Journal Supplement Series, 2018
Abstract 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. We present 838 outer solar system discoveries that are entirely free of ephemeris bias.

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 ...

Gravitomagnetism and the Earth-Mercury range

, 2011
We numerically work out the impact of the general relativistic Lense-Thirring effect on the Earth-Mercury range caused by the gravitomagnetic field of the rotating Sun.

Stellar occultations by trans-Neptunian objects

The Astronomy and Astrophysics Review
Stellar occultations provide a powerful tool to explore objects of the outer solar system. The Gaia mission now provides milli-arcsec accuracy on the predictions of these events and makes possible observations that were previously unthinkable. Occultations return kilometric accuracies on the three-dimensional shape of bodies irrespective of their ...

Rotational properties of Centaurs and Trans-Neptunian Objects [PDF]

Astronomy & Astrophysics, 2008
Context. The knowledge of the rotational periods of the small bodies in the outer Solar System is a useful tool for retrieving information on the internal structure of the observed objects and for having hints on the collisional evolution state of the whole population. Aims.

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.

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.

The Possibility of Mirror Planet as Planet Nine in the Solar System

Universe, 2022
A series of dynamical anomalies in the orbits of distant trans-Neptunian objects points to a new celestial body (usually named Planet Nine) in the solar system.
