- Abstract
High-precision astrometry, applied to extrasolar planet detection,
promises to be the most suitable technique to complement the increasing
population of exoplanets detected by radial velocity surveys.
At radio-wavelengths, present ground-based arrays already provide
astrometric precisions at microarcsec levels, comparable to those planned
by future space-based instruments. The necessary boost in sensitivity will
come from future instruments, such as the Square Kilometer Array, which will
provide both the sensitivity and resolution needed for a survey of
stars to contribute significantly to the planetary search.
