凤凰号是由国家海洋局建造的高分辨率近红外光谱仪，于2001年12月首次用于双子座南望远镜。之前在基特峰2.1米和4米望远镜上，凤凰号收到了一个新的探测器，以及改进的制冷、安装和处理设备，然后被送往双子座南。使用两个像素的狭缝，分辨率达到75000，使凤凰号成为目前6-10米级望远镜上分辨率最高的红外光谱仪。讨论了仪器的改进和性能。简要回顾了麦哲伦星云星、棕矮星、主序星和外来恒星的一些研究成果。
Phoenix, a high resolution near-infrared spectrograph build by NOAO, was first used on the Gemini South telescope in December 2001. Previously on the Kitt Peak 2.1 and 4 meter telescopes, Phoenix received a new detector, as well as modified refrigeration, mounting, and handling equipment, prior to being sent to Gemini South. Using a two-pixel slit the resolution is ~75,000, making Phoenix the highest resolution infrared spectrograph available on a 6-10 meter class telescope at the current time. Modifications to and performance of the instrument are discussed. Some results on Magellanic cloud stars, brown dwarf stars, premain-sequence objects, and stellar exotica are reviewed briefly.
