Hunting for Hydrated Minerals on Trans-Neptunian Objects [PDF]

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

The Trans-Neptunian Objects

EAS Publications Series, 2010
Trans-neptunian objects (TNOs) are believed to be pristine remnants of planets formation, providing constrains on the early stages of the solar system evolution. The knowledge of this population composition and dynamics provides constrains on the formation processes of the early solar nebula, as well as formation processes of other planetary systems ...

Shepherding in a Self-gravitating Disk of Trans-Neptunian Objects. [PDF]

Astron J, 2019
Abstract A relatively massive and moderately eccentric disk of trans-Neptunian objects (TNOs) can effectively counteract apse precession induced by the outer planets, and in the process shepherd highly eccentric members of its population into nearly stationary configurations that are antialigned with the disk itself. We were sufficiently

FOSSIL. III. Lightcurves of 371 Trans-Neptunian Objects

The Astrophysical Journal Supplement Series, 2023
From the first phase of the high-cadence Formation of the Outer Solar System: an Icy Legacy (FOSSIL) survey, we analyzed lightcurves, ranging from one to four nights in length, of 371 trans-Neptunian objects (TNOs) for periodicity.

Taxonomy of Centaurs and Trans-Neptunian Objects [PDF]

The Astronomical Journal, 2005
Trans-Neptunian objects (TNOs) and Centaurs display the widest color diversity in comparison to other small solar system bodies. The investigation of their properties can help in understanding the evolution of these objects. In this paper we propose a classification scheme based on multivariate statistical analysis of a homogeneous, high-quality set of

TNOs are Cool: A Survey of the Trans-Neptunian Region: Radiometric properties of Trans-Neptunian Objects [PDF]

, 2010
The "TNOs are Cool: A Survey of the Trans-Neptunian Region" project is a Herschel Open Time Key Program awarded some 370 h of Herschel observing time. The observations include PACS and SPIRE point-source photometry on about 140 trans-Neptunian objects with known orbits.

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 ...

Taxonomy and densities of Trans-Neptunian Objects

, 2010
A Large Programme at ESO has been devoted to the investigation of Centaurs and Trans-Neptunian Objects. In this framework the photometric colors and the light curves of selected targets have been acquired. Here we present and discuss all the results obtained from the photometric technique.
