AST-9619418 A Survey of Nearby Stars for Extrasolar Planets. Drs. Steven Vogt, Geoffrey Marcy, and Paul Butler will use the Keck I telescope in Hawaii and the HIRES spectrometer on that telescope to carry out an initial 2-year reconnaissance program to survey about 400 nearby stars for giant planets. With this system they have already proven they can reach a precision of 3 m/s with their Doppler technique to provide detections of Jupiter- mass planets within 5 Astronomical Units of the parent star. Refinement of the Doppler analysis will enable detection of Saturn-mass planets at 5 Astronomical Units from the parent star. =================================

AST-9619418 太阳系外行星的邻近恒星巡天。 史蒂芬沃格特博士、杰弗里马西博士和保罗巴特勒博士将使用夏威夷的凯克一号望远镜和该望远镜上的HIRES光谱仪，进行为期两年的初步侦察计划，调查大约400颗附近的恒星，寻找巨行星。 有了这个系统，他们已经证明，他们可以达到3米/秒的精度与他们的多普勒技术，以提供探测木星质量的行星在5个天文单位的母星星。 对多普勒分析的改进将使探测到距离母星星5个天文单位的土星质量行星成为可能。 =================================
