An Ishigaki International Conference on

Evolving Theory for Planet Formation

June 20-26, 2010, Ishigaki Island, Okinawa, Japan

                                                                                           [4D2U, NAOJ]


Planet formation theories have been stimulated by observations of protoplanetary disks, exoplanets, debris disks, and Saturnian ring. In particular, the diversity of extrasolar planets forces theorists to change and generalize the model for formation of the solar system. Here we summarize the observational constrains, review the current status, and discuss the future perspectives of theories for planet formation.

Ishigaki island has two observatories, VERA (VLBI, radio) and Ishigaki observatory (optical, IR), of National Astronomical Observatory Japan. Every summer Ishigaki enjoys a famous star festival. So, Ishigaki is now known as "an island of stars," as well as a subtropical island with its beautiful nature and traditional culture. Let's enjoy discussion on planet formation on the habitable island!
