Development of a Near-Infrared Imager/Spectrograph for Fan Mountain Observatory

这个项目将为弗吉尼亚大学的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制造该仪器，该仪器基于1024x1024 HgCdTe罗克韦尔科学中心“夏威夷”阵列，提供对2.5微米波长的灵敏度。除了宽带和窄带成像能力外，该相机的设计还包括基于低分辨率(R~300)的光谱分析模式。完成的系统将用于几个科学应用，包括1.年轻恒星物体的可变性研究，2.棕矮星的光谱分类研究，棕矮星的视差/自行测量，3.渐近巨型分支恒星的分类和可变性研究，以及4.小行星和近地天体的旋转矿物学研究。***

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. ***
