Strategic Explorations of Exoplanets and Disks with Subaru

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 hundreds of nearby stars.

[2] The survey's headquarters is at the National Astronomical Observatory of Japan (NAOJ) and led by Principal Investigator Motohide Tamura.

[2] The survey also discovered a likely superjovian-mass planet named Kappa Andromedae b, orbiting a young B-type star 2.8 times the mass of Sun.

[8] HD 100546 b was confirmed as a planet with a disk system around a very young star as part of the SEEDS survey.

These disks exhibit gaps, spiral arms, rings, and other structures at similar radial distances where the outer planets are imaged.
