Detection of transit of exo planet with long orbital period from Antarctica

在南极富士圆顶高原上成功安装了一台长周期太阳系外行星过境观测相机，该相机具有两个相同的相机，但不同的滤光片。长周期的太阳系外行星表面温度较低，由于夜间持续时间长，富士圆顶是探测长周期现象的最佳地点。不幸的是，在南极冬季的远程调整工作中，电源模块发生了故障，导致我们无法获取科学数据。动力模块由第54南极考察队修复，目前正在进行远程恢复工作。除了凌日观测之外，我们还在圆顶富士做了一些选址评估，为不久的将来一个可能的天文观测站选址。富士圆顶的可降水量（PWV）即使在夏季也很低（约5 mm），仅为莫纳克亚山最佳季节值的1/2 ~ 1/3。在南极的冬季，我们可以预计PWV会达到~0.1毫米，因此圆顶富士是地球上已知的红外线天文学的最佳地点之一。

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.
