Scientific paper

Epsilon Eridani is the closest star to the Sun, around which a planet has been discovered. An asymmetric dust disk around the star has been detected in sub-millimeter observations. The clumps in the disk have been interpreted as resulting from resonant interaction, and the pattern has been predicted to revolve around star at a rate of ~0.7^degrees per year. We propose first epoch observations of the dust disk with STIS, to be followed up in subsequent cycles. These observations will not only reveal what may be the first extra-solar `Kuiper belt', but will also provide a crucial step in the development of observational techniques that can determine the presence and properties of planets, from the visible morphology of the disks around the parent stars.
