Running the planetary alert system and search for transit planets

2009年，通过用1.8米望远镜观测银河系隆起区，我们发现了563个微透镜事件，并发出了警报。在他们中间，我们发现了行星异常，并向世界各地发布了警报，以鼓励后续的观测。然后我们找到了4个行星候选者。通过组合到目前为止发现的10颗系外行星，我们发现海王星质量的行星比围绕K，M的木星质量的行星至少常见3倍，在雪线之外。

In 2009, by observing the galactic bulge region with 1.8m telescope, we found 563 microlensing events and issued the alerts. Amang them, we found the planetary anomaly and issued the alert to all around the world to encourage the follow-up observation. Then we found 4 planetary candidates. By combining 10 exoplanets found to date, we found that the Neptune-mass planets are at least 3 times more common than the Jupiter-mass planets around K,M dwarfs beyond the snow line.
