SEEDS -- Direct Imaging Survey for Exoplanets and Disks
Abstract
Exoplanets on wide orbits (r ≳ 10 AU) can be revealed by high-contrast direct imaging, which is efficient for their detailed detections and characterizations compared with indirect techniques. The SEEDS campaign, using the 8.2-m Subaru Telescope , is one of the most extensive campaigns to search for wide-orbit exoplanets via direct imaging. Since 2009 to date, the campaign has surveyed exoplanets around stellar targets selected from the solar neighborhood, moving groups, open clusters, and star-forming regions. It also surveys exoplanets in planetary systems with debris disks . The survey is designed to perform observations of ∼500 stars, covering the age range of 1 Myr to a few Gyr. As a result of the observations performed so far, SEEDS has detected new sub-stellar companions , including planets with properties that are unique compared with the previously directly imaged exoplanets. High-contrast imaging by SEEDS has also provided better characterizations of exoplanet systems identified by indirect techniques.
