We present results from the first three years of observations of moving group (MG) targets in the Strategic Exploration of
Exoplanets and Disks with Subaru (SEEDS) high-contrast imaging survey of exoplanets and disks using the Subaru telescope.
We achieve typical contrasts of ~105 at 1'' and ~106 beyond 2'' around 63 proposed members of nearby kinematic MGs. We review
each of the kinematic associations to which our targets belong, concluding that five, β Pictoris (~20 Myr), AB Doradus (~100
Myr), Columba (~30 Myr), Tucana-Horogium (~30 Myr), and TW Hydrae (~10 Myr), are sufficiently well-defined to constrain the
ages of individual targets. Somewhat less than half of our targets are high-probability members of one of these MGs. For all
of our targets, we combine proposed MG membership with other age indicators where available, including Ca II HK emission,
X-ray activity, and rotation period, to produce a posterior probability distribution of age. SEEDS observations discovered
a substellar companion to one of our targets, κ And, a late B star. We do not detect any other substellar companions, but
do find seven new close binary systems, of which one still needs to be confirmed. A detailed analysis of the statistics of
this sample, and of the companion mass constraints given our age probability distributions and exoplanet cooling models, will
be presented in a forthcoming paper.
