Query: Know the Star, Know the Planet. I. Adaptive Optics of Exoplanet Host
  Stars   The results of an adaptive optics survey of exoplanet host stars for stellar
companions is presented. We used the AEOS Telescope and its adaptive optics
system to collect deep images of the stars in $I$-band. Sixty-two exoplanet
host stars were observed and fifteen multiple star systems were resolved. Of
these eight are known multiples, while seven are new candidate binaries. For
all binaries, we measured the relative astrometry of the pair and the
differential magnitude in $I$-band. We improved the orbits of HD 19994 and
$\tau$ Boo. These observations will provide improved statistics on the
duplicity of exoplanet hosts stars and provide an increased understanding of
the dynamics of known binary star exoplanet hosts.
