A Planet-Hunting Spectrometer for the Magellan Telescope

AST-0116529Butler， PaulA将为新的南半球望远镜麦哲伦建造行星探测仪器（光谱仪）。为位于南半球的麦哲伦望远镜设计、指定、制造、组装和测试一个高分辨率梯队光谱仪。精确的径向速度将被测量，以寻找在恒星轨道上显示小暗体（行星）的特征特征。这种特殊用途的摄谱仪将能够在2到4米/秒的水平上进行多普勒速度变化。这种摄谱仪和望远镜的组合将使超过1000个。新的候选恒星将被用于轨道行星的检查，并代表了天文学家对北半球望远镜无法获得的南半球恒星的第一次深入调查。望远镜/光谱仪系统将提供给麦哲伦社区的成员：哈佛大学、麻省理工学院、密歇根大学、亚利桑那大学和卡内基天文台。＊＊＊

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. ***
