A Southern Hemisphere Search for Extra-Solar Planets

巴特勒，保罗“南半球对太阳系外行星的搜索“AST-9988087国际行星研究所建议将他们在利克天文台和凯克天文台非常成功的太阳系外行星搜索扩展到南半球。 原则上，在银河系的南部会发现更多的恒星和行星，那里的星星密度最大，而且之前对行星的调查工作很少。 最近改进的碘细胞技术测量恒星径向速度率先由PI现在有可能检测“木星和土星的类似物。“这些行星比以前可探测到的质量更小，更正常。 英澳3.9米望远镜将用于观测最近的600颗恒星。 这些结果很可能为空间干涉测量使命的后续观测提供许多行星候选者。该项目的资金由美国国家科学基金会恒星天文学天体物理学计划（AST/SAA）提供。

ABSTRACTButler, Paul"A Southern Hemisphere Search for Extra-Solar Planets"AST-9988087The PIs propose to extend their very successful search for extra-solar planets at Lick Observatory and Keck Observatory to the southern hemisphere. In principle, even more stars harboring planets are to be found in the south, where the Galaxy's star density is greatest and little prior survey work for planets has been done. Recent improvements in the iodine cell technique for measuring stellar radial velocities pioneered by the PIs now have the potential to detect 'Jupiter and Saturn analogs.' These are less massive and more normal planets than previously detectable. The Anglo-Australian 3.9-m telescope will be used to survey the nearest 600 stars. The results are likely to provide many planetary candidates for follow-up observations with the Space Interferometry Mission.Funding for this project was provided by the NSF program for Stellar Astronomy & Astrophysics (AST/SAA).
