Microlensing survey with MOA II 1.8m telescope

使用安装在Mt.的MOA II 1.8米望远镜进行高节奏微透镜测量。约翰天文台，新西兰已执行对银河系的隆起和麦哲伦云。利用真实的时间分析，与全球跟踪网络合作，发现并观察了1696个微透镜候选者。通过对微透镜事件的分析，发现了典型的行星系统，如太阳系类似物、小行星绕小行星、大行星绕小行星。关于行星分布的讨论已经开始。人们发现冷海王星质量行星在我们的银河系中很常见。

High cadence microlensing survey using MOA II 1.8m telescope installed at Mt. John Observatory, New Zealand have been executed toward Galactic bulge and Magellanic clouds. Using real time analysis, 1696 microlensing candidates have been found and observed collaborating with world wide follow-up network. From the analyses of microlensing events, characteristic planetary system such as solar system analogue, small planet around a small host, and giant planet around a small host. Discussion on the distribution of planets has started. Cool Neptune mass planets were found to be common in our Galaxy.
