A Survey of Nearby Stars for Extrasolar Planets

AST-9619418太阳系外行星附近恒星的观测。史蒂文·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I望远镜和该望远镜上的租用光谱仪进行为期两年的初步侦察计划，以调查附近约400颗恒星的巨行星。有了这个系统，他们已经证明，利用他们的多普勒技术，他们可以达到3米/S的精度，可以探测到母星5个天文单位内的木星质量的行星。改进的多普勒分析将能够从母星的5个天文单位探测到土星质量的行星。=

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. =================================
