AST-0216256Skrutskie, Michael F.This project will equip the University of Virginia's Fan mountain observatory with a state-of-the-art infrared imager. Graduate and undergraduate students will design and build the instrument, which is based on a 1024x1024 HgCdTe Rockwell Science Center "HAWAII" array to provide sensitivity to 2.5 micrometers wavelength. In addition to broad and narrow-band imaging capabioity the camera design includes a low resolution (R~300) grism-based spectrographic mode. The completed system will be used for several scientific applications, including 1.variability studies of young stellar objects, 2. Spectral classification studies of brown dwarfs, parallax/proper motion measurements of brown dwarfs, 3. Classification and variability studies of asymptotic giant branch stars, and 4 rotational mineralogy studies of asteriods and near-earth objects. ***

AST-0216256Skrutskie，Michael F。该项目将为弗吉尼亚大学范山天文台配备最先进的红外成像仪。研究生和本科生将设计和建造该仪器，该仪器基于 1024x1024 HgCdTe 罗克韦尔科学中心“HAWAII”阵列，可提供对 2.5 微米波长的灵敏度。除了宽带和窄带成像功能之外，相机设计还包括基于低分辨率 (R~300) 光栅的光谱模式。完整的系统将用于多项科学应用，包括1.年轻恒星物体的变异性研究，2.褐矮星的光谱分类研究，褐矮星的视差/自行测量，3.渐近巨分支星的分类和变异性研究，以及4.小行星和近地天体的旋转矿物学研究。 ***
