Probing Protoplanetary Disks in the SEEDS project.

I have been a member of SEEDS project: Strategic Explorations of Exoplanets and Disks with Subaru Telescope (Tamura 2009). In SEEDS, we are exploring exoplanets and protoplanetary disks around 500 stars using 120 nights of Subaru for 5 years. I’m particularly interested in protoplanetary disks. Protoplanetary disk is a by-product of star formation and has been believed to be a birthplace of a planet. Therefore, many observational studies have been conducted to understand planet formations so far. In this talk, I will review the SEEDS disk results and present my studies in SEEDS.
