AU Mic is a nearby Vega-type debris disk star. Its disk system has been spatially resolved in exquisite detail, predominantly via the ACS coronagraph and WFPC-2 cameras onboard HST. These images exhibit a wealth of morphological features which provide compelling indirect evidence that AU Mic likely harbors short-period planetary body(ies). We propose to use the superlative astrometric capabilities of HST/FGS to directly detect these planets, hence provide the first direct planet detection in a Vega-type system whose disk has been imaged at high spatial resolution.

We will use FGS1r to monitor the position of AU Mic relaive to nearby field stars to investigate the possible presence of Jupiter mass planets in orbit about the star.
