We have searched the four brightest objects in the Kuiper Belt for the presence of satellites using the newly commissioned Keck Observatory Laser Guide Star Adaptive Optics system. Satellites are seen around three of the four objects: Pluto (whose satellite Charon is well-known and whose recently discovered smaller satellites are too faint to be detected), 2003 EL61 (where a second satellite is seen in addition to the previously known satellite), and 2003 UB313 (where a satellite is seen for…

Medium-sized Satellites of Large Kuiper Belt Objects
While satellites of mid- to small-Kuiper belt objects tend to be similar in size and brightness to their primaries, the largest Kuiper belt objects preferentially have satellites with small
Orbits and Masses of the Satellites of the Dwarf Planet Haumea (2003 EL61)
Using precise relative astrometry from the Hubble Space Telescope and the W. M. Keck Telescope, we have determined the orbits and masses of the two dynamically interacting satellites of the dwarf
The largest Kuiper belt objects
While for the first decade of the study of the Kuiper belt, a gap existed between the sizes of the relatively small and faint Kuiper belt objects (KBOs) that were being studied and the largest known
A Deep Search for Additional Satellites around the Dwarf Planet Haumea
Haumea is a dwarf planet with two known satellites, an unusually high spin rate, and a large collisional family, making it one of the most interesting objects in the outer solar system. A fully
Orbital dynamics of Kuiper Belt object satellites, a Kuiper Belt family, and extra-solar planet interiors
This thesis discusses research into four different orbital dynamics problems, where the main goal of each chapter is to characterize the strongest non-Keplerian effect. These problems are introduced
The La Silla-QUEST Kuiper Belt Survey
We describe the instrumentation and detection software and characterize the detection efficiency of an automated, all-sky, southern-hemisphere search for Kuiper Belt Objects (KBOs) brighter than R
Discovery of a Satellite of the Large Trans-Neptunian Object (225088) 2007 OR10
2007 OR10 is currently the third largest known dwarf planet in the trans-Neptunian region, with an effective radiometric diameter of ~1535 km. It has a slow rotation period of ~45 hr that was
The Solar System Beyond The Planets
The Kuiper belt contains a vast number of objects in a flattened, ring-like volume beyond the orbit of Neptune. These objects are collisionally processed relics from the accretion disk of the Sun
A collisional family of icy objects in the Kuiper belt
The discovery of a family of Kuiper belt objects with surface properties and orbits that are nearly identical to those of 2003 EL61, which appears to be fragments of the ejected ice mantle of2003 EL61.
The Formation of the Collisional Family Around the Dwarf Planet Haumea
Haumea, a rapidly rotating elongated dwarf planet ({approx}1500 km in diameter), has two satellites and is associated with a 'family' of several smaller Kuiper Belt objects (KBOs) in similar orbits.


Keck Observatory Laser Guide Star Adaptive Optics Discovery and Characterization of a Satellite to the Large Kuiper Belt Object 2003 EL 61
The newly commissioned laser guide star adaptive optics system at Keck Observatory has been used to discover and characterize the orbit of a satellite to the bright Kuiper Belt object 2003 EL_(61).
The binary Kuiper-belt object 1998 WW31
It is reported that the Kuiper-belt object 1998 WW31 is binary with a highly eccentric orbit (eccentricity e ≈ 0.8) and a long period (about 570 days), very different from the Pluto/Charon system, which was hitherto the only previously known binary in theKuiper belt.
Discovery of a Planetary-sized Object in the Scattered Kuiper Belt
We present the discovery and initial physical and dynamical characterization of the object 2003 UB313. The object is sufficiently bright that for all reasonable values of the albedo it is certain to
Formation of Kuiper-belt binaries by dynamical friction and three-body encounters
It is shown that a transient binary forms when two large bodies penetrate one another's Hill sphere (the region where their mutual forces are larger than the tidal force of the Sun) and the loss of energy needed to stabilize the binary orbit can occur through dynamical friction from surrounding small bodies, or through the gravitational scattering of a third large body.
The Orbit and Albedo of Trans-Neptunian Binary (58534) 1997 CQ29*
We have measured the separations and position angles of the two components of the binary trans-Neptunian object (58534) 1997 CQ29 at eight epochs. From these data we are able to constrain the orbit
Detection of Six Trans-Neptunian Binaries with NICMOS
We have analyzed a homogeneous set of observations of 81 trans-Neptunian objects obtained with NIC2 on the Hubble Space Telescope with the goal of identifying partially resolved binaries. Using PSF
On the origin of the Pluto-Charon binary
The normalized angular momentum density of Pluto-Charon (0.45) exceeds the critical value of 0.39 above which no stably rotating single object exists, suggesting a collisional origin for this binary.
A Giant Impact Origin of Pluto-Charon
Hydrodynamic simulations are used to demonstrate that the formation of Pluto-Charon by means of a large collision is quite plausible, and suggest that collisions between 1000-kilometer-class objects occurred in the early inner Kuiper belt.
