The collisional family of Kuiper Belt object (KBO) 2003 EL61 opens the possibility for many interesting new studies of processes important in the formation and evolution of the outer solar system. As the first family in the Kuiper Belt, it can be studied using techniques developed for studying asteroid families, although some modifications are necessary. Applying these modified techniques allows for a dynamical study of the 2003 EL61 family. The velocity required to change orbits is used to… Expand

On a Scattered-Disk Origin for the 2003 EL61 Collisional Family
The recent discovery of the 2003 EL61 collisional family in the Kuiper belt by M. Brown and collaborators is surprising because the formation of such a family is a highly improbable event in today'sExpand
Detection of Additional Members of the 2003 EL61 Collisional Family via Near-Infrared Spectroscopy
We have acquired near-infrared spectra of Kuiper Belt objects 2003 UZ117, 2005 CB79, and 2004 SB60 with NIRC on the Keck I telescope. These objects are dynamically close to the core of the 2003 EL61Expand
Size and albedo of Kuiper belt object 55636 from a stellar occultation
Observations of a multi-chord stellar occultation by KBO 55636, which occurred on 9 October 2009, find that it has a mean radius of 143 ± 5 km and a geometric albedo of in the V photometric band, which establishes that KBO55636 is smaller than previously thought and that, like its parent body, it is highly reflective.

The effect of orbital evolution on the Haumea (2003 EL61) collisional family
Abstract The Haumea family is currently the only identified collisional family in the Kuiper belt. We numerically simulate the long-term dynamical evolution of the family to estimate a lower limit ofExpand

Long-term dynamical stability of the Haumea (2003 EL61) collisional family
The Haumea family is so far the only identified collisional family in the Kuiper belt [1]. The formation of the family occurred at least 1 Gyr ago, but it most likely occurred in the primordialExpand
