AST 0349360 CloseDr. Laird Close, at the University of Arizona, will undertake two large surveys to directly detect extrasolar planets around 49 young, and 51 nearby, stars with novel optical devices called quadrant simultaneous differential imagers (SDI). The quadrant SDI has been developed by Dr. Close to reveal the presence of an extrasolar gas giant by a double difference of 4 images taken simultaneously. Based on current models of the properties of extra-solar planets he expects to detect of order 3-10 extrasolar planets by the end of these surveys.Support from this CAREER grant will enable Dr. Close to train a new generation of young graduate student astronomers in the field of extrasolar planetary science and adaptive optics. The PI will also use this grant to complete the first dedicated research quality IR telescope for public outreach and education. This new IR facility will play a key role in giving interactive, hands-on, experience observing the invisible infrared universe to teenagers, and in the training of adult Girl Guide leaders in biannual workshops to be held at the Mt. Lemmon/Astronomy Camp site as part of the Observatory's "Linking Girls with the Sky" outreach program.

AST 0349360 close博士亚利桑那大学的Laird Close将进行两次大型调查，直接探测49颗年轻恒星和51颗附近恒星周围的太阳系外行星，这些恒星使用一种叫做象限同步差分成像仪（SDI）的新型光学设备。SDI象限是由克洛斯博士开发的，通过同时拍摄的四张图像的双差来揭示太阳系外气体巨星的存在。基于目前太阳系外行星特性的模型，他希望在这些调查结束时能探测到3-10颗太阳系外行星。这项职业补助金将使Close博士能够在系外行星科学和自适应光学领域培养新一代年轻的研究生天文学家。PI还将使用这笔拨款来完成第一个专门研究质量的红外望远镜，用于公众宣传和教育。这个新的红外设施将发挥关键作用，为青少年提供互动的、实际的、观察不可见红外宇宙的经验，并在每年两次的研讨会上培训成年女童军领导人，该研讨会将在莱蒙山/天文学营地举行，作为天文台“将女孩与天空联系起来”外展计划的一部分。
