The Subaru SEEDS Direct Imaging Survey for Planets of Early-Type Stars

We present results from the Subaru SEEDS sub-program to search for extrasolar planets around early-type (mostly A-type) stars. SEEDS, the Strategic Exploration of Exoplanets and Disks with Subaru, is a multi-year, direct-imaging survey to explore the link between planets and disks, and the evolution of protoplanetary systems and debris disks. With first observations carried out in 2009, the early-type star sub-program uses the Subaru 8-meter Telescope, the AO188 adaptive optics system, the HiCIAO near infrared science camera, and an Angular Differential Imaging observing procedure to distinguish faint orbiting companions from the overwhelming light of the parent star. We summarize progress to date, including the nature of our data processing techniques, improved software sensitivities, and our prior discovery of the 'Super-Jupiter' Kappa Andromedae b.
