Are Two of the Neptune Trojans Dynamically Unstable? [PDF]

, 2012
The Neptune Trojans are the most recently discovered population of small bodies in the Solar System. To date, only eight have been discovered, though it is thought likely that the total population at least rivals that of the asteroid 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 ...

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.

Primordial Orbital Alignment of Sednoids

The Astrophysical Journal Letters
We 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 .

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

Weywot, an Unusually Low-albedo Satellite in the Trans-Neptunian Region

The Astrophysical Journal Letters
Weywot is the largest satellite of the candidate dwarf planet Quaoar, which also hosts a remarkable ring system located beyond its Roche limit—a configuration that challenges conventional understanding of ring dynamics.

Detection of Close Kuiper Belt Binaries with HST WFC3

The Planetary Science Journal
Binaries 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 ...

Dynamics of the Kuiper Belt [PDF]

, 1999
Our current knowledge of the dynamical structure of the Kuiper Belt is reviewed here. Numerical results on long term orbital evolution and dynamical mechanisms underlying the transport of objects out of the Kuiper Belt are discussed.

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.
