AST-0116529Butler, PaulA planet-hunting instrument (spectrometer) for the new Southern Hemisphere telescope: Magellan will be built. A high-resolution echelle spectrograph for the southern hemisphere-located Magellan Telescope will be designed, specified, fabricated, assembled and tested. Precision radial velocities will be measured to look for the characteristic signature that indicates small dark bodies (planets) in orbit about a star. This special purpose spectrograph will be able to Doppler velocity changes, at the level of 2 to 4 m/sec. This spectrograph-telescope combination will enable over 1,000. new candidate stars to be examined for orbiting planets and represents the astronomy community's first in-depth survey of those Southern Hemisphere stars not available from Northern Hemisphere telescopes. The telescope/spectrograph system will be available to members of the Magellan community: Harvard, MIT, Michigan, Arizona and Carnegie Observatories. ***

AST-0116529巴特勒，保罗一个行星狩猎仪器（光谱仪）的新南半球望远镜：麦哲伦将建成。将为位于南半球的麦哲伦望远镜设计、指定、制造、组装和测试一台高分辨率中阶梯光栅摄谱仪。精确的径向速度将被测量，以寻找表明围绕星星运行的小暗体（行星）的特征信号。这种特殊用途的摄谱仪将能够多普勒速度的变化，在2至4米/秒的水平。 这种摄谱仪-望远镜组合将使超过1000。新的候选恒星将被检查的轨道行星，并代表天文学界的第一次深入调查，这些南半球的恒星无法从北方半球望远镜。 望远镜/摄谱仪系统将提供给麦哲伦社区的成员：哈佛、麻省理工学院、密歇根、亚利桑那和卡内基天文台。***
