Primordial Orbital Alignment of Sednoids
The Astrophysical Journal LettersWe examined the past history of the three most detached trans-Neptunian objects (TNOs)—Sedna, 2012 VP _113 , and Leleakuhonua (2015 TG _387 )—the three clearest members of the dynamical class known as sednoids, with high perihelia distances q .

Limits on Stellar Flybys in the Solar Birth Cluster
The Astrophysical Journal LettersThe 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 ...

Synchronous Rotation in the (120347) Salacia–Actaea System
The Planetary Science JournalWe report on roughly 16 yr of photometric monitoring of the trans-Neptunian binary system (120347) Salacia–Actaea, which provides significant evidence that Salacia and Actaea are tidally locked to the mutual orbital period in a fully synchronous ...

The absolute magnitude distribution of trans-Neptunian objects [PDF]
Monthly Notices of the Royal Astronomical Society, 2003 It is shown that the known trans-Neptunian objects (TNOs) have an absolute magnitude distribution index that increases as a function of orbital perihelion distance. In no perihelion range is the TNO index the same as that found for known short-period comets.

Detection of Close Kuiper Belt Binaries with HST WFC3
The Planetary Science JournalBinaries in the Kuiper Belt are common. Here we present our analysis of the Solar System Origins Legacy Survey (SSOLS) to show that using a point-spread function (PSF)-fitting method can roughly double the number of binaries identified in that data set ...

Collisional evolution of asteroids and Trans–Neptunian objects [PDF]
Proceedings of the International Astronomical Union, 2005 Since Pietrowsky's first analytical study of collisional systems of asteroids (1953), through Dohnanyi's comprehensive theory (1969), to the analytical and numerical studies of the last two decades, the collisional evolution of populations of asteroids — and to a less extent, of Trojans and TNOs— has been investigated by many researchers. The study of

A Near-infrared Survey of Candidate Haumea Family Members
The Astronomical JournalThe Haumea family is the only known dynamical family in the trans-Neptunian region. To date, 10 family members have been unambiguously identified using near-infrared (NIR) spectral or photometric data in combination with their strong dynamical proximity ...

Compositional Surface Diversity in the Trans-Neptunian Objects
The Astronomical Journal, 2000 The knowledge of the physical and chemical properties of trans-Neptunian objects (TNOs) is still incomplete and confused. To investigate their physical properties, we are continuing the TNO observational program started in 1997 at ESO in La Silla, Chile with the 3.5 m New Technology Telescope.

The Inner Kernel of the Classical Kuiper Belt
The Astrophysical Journal LettersThe “kernel” of the classical Kuiper Belt was discovered by Petit et al. as a visual overdensity of objects with low ecliptic inclinations and eccentricities at semimajor axes near ∼44 au.
