Strategic Explorations of Exoplanets and Disks with Subaru

The Subaru Telescope at the Mauna Kea Observatory on Hawaii.

Strategic Explorations of Exoplanets and Disks with Subaru (SEEDS) is a multi-year survey that used 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 was 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 dozens of institutes around the world. Observations began in late October 2009, and finished in early January 2015. 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

Kappa Andromedae b, the Super-Jupiter exoplanet of 12.8 Jupiter masses discovered as part of the SEEDS survey
The confirmed brown dwarf GJ 758 B and the candidate GJ 758 C, which was later found to be a background star
