The scattered trans-Neptunian object 1998 XY95 [PDF]

Monthly Notices of the Royal Astronomical Society, 2001
On 1998 December 12 a new trans-Neptunian object, 1998 XY95, was discovered as part of a deep search. Recent observations of this object have placed it amongst the class of objects known as the scattered trans-Neptunian objects (TNOs). A total of 39 CCD images of 1998 XY95 were taken over two nights, and these were used to search for a light curve, but

Resonant motion of trans-Neptunian objects in high-eccentricity orbits

, 2008
A substantial fraction of the Edgeworth-Kuiper belt objects are presently known to move in resonance with Neptune (the principal commensurabilities are 1/2, 3/5, 2/3, and 3/4). We have found that many of the distant (with orbital semimajor axes a > 50 AU)

The DECam Ecliptic Exploration Project (DEEP). VI. First Multiyear Observations of Trans-Neptunian Objects

The Astronomical Journal
We present the first set of trans-Neptunian objects (TNOs) observed on multiple nights in data taken from the DECam Ecliptic Exploration Project. Of these 110 TNOs, 105 do not coincide with previously known TNOs and appear to be new discoveries.

Rotational Study of 5:3 and 7:4 Resonant Objects within the Main Classical Trans-Neptunian Belt

The Planetary Science Journal
The 5:3 and 7:4 mean motion resonances of Neptune are at 42.3 and 43.7 au, respectively, and overlap with objects in the classical trans-Neptunian belt (Kuiper Belt).

Spectrophotometry of Trans-Neptunian Objects

, 2000
International audienceThe Trans-Neptunian Objects (TNOs) are very difficult to observe due to their faintness. Spectra can be obtained for only few objects.

Characterizing neutral Trans-Neptunian Objects [PDF]

, 2013
Trans-Neptunian Objects (TNOs) are small bodies with orbits beyond Neptune (3050 AU). TNOs are cold and small enough to have remained relatively well-preserved, therefore providing our best observable proxy to the early solar system.

Polarimetry of trans-Neptunian objects (136472) Makemake and (90482) Orcus

, 2012
Context. We study the surface properties of trans-Neptunian populations of solar system bodies. Aims. We investigate the surface characteristics of the dwarf planet (136472) Makemake and the resonant object (90482) Orcus. Methods.

Logos-Zoe: A Contact Binary Triple System in the Trans-Neptunian Belt

The Astronomical Journal
The trans-Neptunian object (58534) 1997 CQ _29 (a.k.a. Logos) is a resolved wide binary in the dynamically Cold Classical population. With Hubble Space Telescope resolved observations where the primary Logos is well separated from its secondary Zoe it ...

Limits on Stellar Flybys in the Solar Birth Cluster

The Astrophysical Journal Letters
The orbits of small bodies in the outer solar system are particularly sensitive to gravitational perturbations, including stellar flybys. Stellar clusters, with low velocity dispersions and high number densities, can be the source of strong and frequent ...
