A Sedna-like body with a perihelion of 80 astronomical units
The observable Solar System can be divided into three distinct regions: the rocky terrestrial planets including the asteroids at 0.39 to 4.2 astronomical units (au) from the Sun (where 1 au is theExpand

The Albedo Distribution of Jovian Trojan Asteroids
We present radiometrically derived V-band geometric albedos and effective radii for 32 Jovian Trojan asteroids, using near-simultaneous mid-infrared and visible observations. We sampled the large endExpand

High albedos of low inclination Classical Kuiper belt objects
Abstract We present observations of thermal emission from fifteen transneptunian objects (TNOs) made using the Spitzer Space Telescope . Thirteen of the targets are members of the ClassicalExpand

Time-resolved photometry of kuiper belt objects: rotations, shapes and phase functions
We present a systematic investigation of the rotational light curves of trans-Neptunian objects based on extensive optical data from Mauna Kea. Four of 13 objects (corresponding to 31%) in our sampleExpand

A New Population of High-Redshift Short-Duration Gamma-Ray Bursts
The redshift distribution of the short-duration gamma-ray bursts (GRBs) is a crucial, but currently fragmentary,Expand

Physical Properties of Trans-Neptunian Object (20000) Varuna
We present new time-resolved photometric observations of the bright trans-Neptunian object (20000) Varuna and use them to study the rotation period, shape, and color. In observations from 2001Expand

Light Curves of Dwarf Plutonian Planets and other Large Kuiper Belt Objects: Their Rotations, Phase Functions, and Absolute Magnitudes
I report new time-resolved light curves and determine the rotations and phase functions of several large Kuiper Belt objects, which includes the dwarf planet Eris (2003 UB313). Three of the newExpand

A Thick Cloud of Neptune Trojans and Their Colors
The dynamical and physical properties of asteroids offer one of the few constraints on the formation, evolution, and migration of the giant planets. Trojan asteroids share a planet's semimajor axisExpand

Size and albedo of Kuiper belt object 55636 from a stellar occultation
The Kuiper belt is a collection of small bodies (Kuiper belt objects, KBOs) that lie beyond the orbit of Neptune and which are believed to have formed contemporaneously with the planets. Their smallExpand
