Trans-Neptunian Objects Found in the First Four Years of the Dark Energy Survey [PDF]

Astrophysical Journal Supplement Series, 2019
We present a catalog of 316 trans-Neptunian bodies (TNOs) detected from the first four seasons (“Y4” data) of the Dark Energy Survey (DES). The survey covers a contiguous 5000 deg2 of the southern sky in the grizY optical/NIR filter set, with a typical ...

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.

Experimental Vapor Pressure Determination for C2H4, C2H6, CH3OH, CH4, CO, CO2, H2O, and N2 Molecules for Astrophysical Relevant Temperatures. Implications for the Presence of Volatiles in Kuiper Belt Objects and Trans-Neptunian Objects

Astrophysical Journal
Vapor pressure is a relevant quantity that is necessary in order to improve the study of the atmosphere dynamics that take place within astrophysical scenarios.

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-

Col-OSSOS: The Two Types of Kuiper Belt Surfaces

The Planetary Science Journal, 2023
The Colors of the Outer Solar System Origins Survey (Col-OSSOS) has gathered a high-quality, near-simultaneous, and brightness-complete sample of ( g − r ) and ( r − J ) colors for 102 Kuiper Belt objects (KBOs) with ( u − g ) and ( r − z ) gathered for ...

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.

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 ...

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 ...

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).

FindPOTATOs: Minor Planet Observation Linking Software

The Planetary Science Journal
For minor planet observations to be archived and used by the scientific community, observations of individual objects must be linked together into groups called tracklets.
