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.

Probing close-in satellites of trans-Neptunian objects through thermal and direct size measurements

Astronomy & Astrophysics
Context. Trans-Neptunian objects are distant bodies that retain valuable information about the origin and evolution of the Solar System. Many of these objects constitute binary systems.

Chemical Evolution of Isotopically Labeled Carbon Dioxide (13CO2) Ice Exposed to Ionizing Radiation and Implications for Trans-Neptunian Objects

The Astrophysical Journal
We present results on the radiation chemistry of isotopically labeled carbon dioxide ( ^13 CO _2 ) ices induced by energetic electrons at 40 and 10 K to simulate the chemical evolution of carbon dioxide on trans-Neptunian objects exposed to galactic ...

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). 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.

Photometry of Kuiper Belt Objects in Inner and Outer Mean Motion Resonances with Neptune

The Astronomical Journal
We present a time-resolved photometric survey of Kuiper Belt Objects (KBOs) trapped in the inner and outer Neptune resonances. Lightcurves and rotational properties provide constraints on the shapes, internal structures, collisional histories, and ...

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).

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 ...

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 ...
