Results from the Subaru Telescope SEEDS Project:

Direct Imaging of Exoplanets and Their Forming Disks

Prof. Motohide Tamura


    Astronomers have successfully discovered a number of extrasolar planets over the last twenty years. Our interests are now focused on direct detection of exoplanets similar to Jupiter, Saturn and Earth, understanding the similarities or diversities of such planetary systems, and how they form and evolve. Recent advances in technology, infrared imaging and the construction of large telescopes have provided dramatic progress in such studies.

    SEEDS (Strategic Explorations of Exoplanets and Disks) is an ongoing large survey for exoplanets and protoplanetary disks at Subaru, one of the largest optical and infrared telescopes in the world. We describe the outline of this survey and present results from its first three years, including the detection of several new planets/companions. We also show our discoveries of the detailed structures of protoplanetary disks, i.e., potential signposts of young planets.
