GO 11113: Binaries in the Kuiper Belt: Probes of Solar System Formation and Evolution
A composite of HST images of the Kuiper Belt binary, WW31 | The Kuiper Belt consists of icy planetoids that orbit the Sun within a broad band stretching from Neptune's orbit (~30 AU) to distance sof ~50 AU from the Sun (see David Jewitt's Kuiper Belt page for details). Over 500 KBOs are currently known out of a population of perhaps 70,000 objects with diameters exceeding 100 km. Approximately 2% of the known KBOs are binary (including Pluto, one of the largest known KBOs, regardless of whether one considers it a planet or not). This is a surprisingly high fraction, given the difficulties involved in forming such systems and the relative ease with which they can be disrupted. It remains unclear whether these systems formed from single KBOs (through collisions or 3-body interactions) as the Kuiper Belt and the Solar System have evolved, or whether they represent the final tail of an initial (much larger) population of primordial binaries. This proposal will use WFPC2 imaging of known KBOs to identify new binary systems. |

Galaxy mergers and the red sequence
The overwhelming majority of galaxies are found in clusters. Observations show
that almost all well-defined cluster systems at low and moderate redshift have a
significant population of elliptical galaxies
which have red colours, indicative of old stellar populations and minimal current star formation.
The elliptical galaxies outline a distinct sequence in the colour-magnitude (or colour-mass) diagram, the
so-called
