Strategic Explorations of Exoplanets and Disks with Subaru (SEEDS) is a multi-year survey that uses the Subaru Telescope on Mauna Kea, Hawaii in an effort to directly image extrasolar planets and protoplanetary/debris disks around several hundred nearby stars.[1] Near-infrared imaging is carried out using the AO188 Adaptive Optics System[2] and HiCIAO high-contrast imaging instrument.[3][4][5] The survey is headquartered at National Astronomical Observatory of Japan (NAOJ) and led by Principal Investigator Motohide Tamura. The survey team includes over a hundred members from several tens of institutes around the world. Observations began in 2009 and are ongoing. The goals of the survey are to address the following key issues in exoplanet∕disk science: (1) the detection and census of exoplanets in the outer circumstellar regions around stars, (2) the evolution of protoplanetary and debris disks including their morphological diversity, and (3) the link between exoplanets and circumstellar disks.

Results[edit]
