A Survey of Nearby Stars for Extrasolar Planets

AST-9619418对太阳系外行星附近恒星的调查。Drs。Steven Vogt， Geoffrey Marcy和Paul Butler将使用位于夏威夷的Keck I望远镜和该望远镜上的HIRES光谱仪执行一项为期两年的初步侦察计划，以调查大约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用多普勒技术达到3米/秒的精度，在距离母恒星5个天文单位的范围内探测木星质量的行星。对多普勒分析的改进将使我们能够在距离母恒星5个天文单位的地方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. =================================
