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-

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.

Scenarios for the Origin of the Orbits of the Trans-Neptunian Objects 2000 CR105 and 2003 VB12

, 2004
Explaining the origin of the orbit of 2000 CR105 (a ~ 230AU, q ~ 45AU) is a major test for our understanding of the primordial evolution of the outer Solar System. Gladman et al.

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.

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 ...

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.

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.

Millisecond dips in the 2007-2009 RXTE/PCA lightcurve of Sco X-1 and one possible occultation event

, 2010
Serendipitous stellar occultation search is so far the only way to detect the existence of very small, very dim, remote objects in the solar system.

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 ...

The angular momentum of two collided rarefied preplanetesimals and the formation of binaries

, 2009
This paper studies the mean angular momentum associated with the collision of two celestial objects in the earliest stages of planet formation. Of primary concern is the scenario of two rarefied preplanetesimals (RPPs) in circular heliocentric orbits ...
