| Research Abstract |
A transit survey camera for long-period extra-solar planet, which has two identical camera but different color filters, was successfully installed at Dome Fuji in Antarctica plateau. Long-period extra-solar planet is expected to have low surface temperature, and Dome Fuji is best location for detecting long-period phenomenon because of the long continuous night. Unfortunately, the power module was broken during remote adjustment work in Antactic winter and we were unable to obtain scientific data. The power module were repaired by 54th Antarctica expedition team and currently doing recovering work from remote. In addition to the transit survey, we did some site evaluation at Dome Fuji for a possible astronomical observatory site in near future. The precipitable water-vapor (PWV) at Dome Fuji was very low (Th. 5 mm) even in summer, which is 1/2-1/3 of the best season value of Mauna Kea. We can expect PWV become ~0.1 mm in Antarctic winter and thus Dome Fuji is one of the best site know on the earth for infrared astronomy.
