This award supports the largest and most sensitive direct imaging survey for extrasolarplanets conducted to date. The NICI (Near-Infrared Coronagraphic Imager) is the newhigh contrast adaptive optics instrument for the Gemini-South 8.1-meter telescope,tailored to direct detection of extrasolar planets through dual-channel methane-bandimaging. NICI will provide excellent sensitivity to planetary ( 1 Jupiter Mass)companions around young ( 1 Million years) stars in the extended solar neighborhood.Specifically, key preparatory activities will be undertaken during the beginning of asignificant multi-year imaging search for extrasolar planets. These include optimizingobserving and analysis algorithms, conducting the observations on-site for the first 25%of the team's awarded time, and pursuing prompt follow-up of newly identified planetarycompanions. It is anticipated that these observations may well yield the firstunambiguous extrasolar planets found by direct imaging.The research goals of this work will be accomplished in tandem with the training of apostdoc in the rapidly growing fields of exoplanets and science with adaptive optics, aswell as hands-on experience with real-time observing on an 8-meter telescope.This work is funded from the Stellar Astronomy and Astrophysics program of theDivision of Astronomical Sciences, as a Small Grant for Exploratory Research.

该奖项支持迄今为止对太阳系外行星进行的规模最大、最灵敏的直接成像调查。NICI（近红外日冕成像仪）是Gemini-South 8.1米望远镜的最新对比度自适应光学仪器，专门用于通过双通道甲烷波段成像直接探测太阳系外行星。NICI将为太阳系外行星的重要多年成像搜索工作的开始提供对太阳系外行星年轻恒星（1百万年）周围的行星（1木星质量）伴星的极好的灵敏度。这些包括优化观测和分析算法，在团队获得的前25%的时间内进行现场观测，并对新发现的行星同伴进行及时的跟踪。预计这些观测很可能产生第一个通过直接成像发现的不明太阳系外行星。这项工作的研究目标将与apostdoc在快速增长的系外行星和自适应光学科学领域的培训同步完成，以及在8- 10米高空实时观察的实践经验，这项工作是由天文科学部的恒星天文学和天体物理学计划资助的，作为探索性研究的小额赠款。
