The Anglo-Australian Planet Search

巴特勒：在过去的7年里，大约有100颗太阳系外行星被发现，这些行星都是通过精确的多普勒速度技术发现的。到目前为止，探测到的行星深刻地挑战了行星形成和进化的理论，并推动了重大的太空任务。国际和平组织将通过英澳星球搜索计划在南半球继续这项工作。这是南半球唯一一个达到探测真正的“太阳系类比”(即木星和土星质量超过4个天文单位(地-太阳距离)的行星)所需的精确度的计划。随着基于他们的成功而增加的望远镜访问，PI将增加他们的目标列表，包括最近和最亮的250颗南半球恒星，提供对附近恒星的第一次行星普查。这项工作被认为为天体生物学和太阳系外行星研究的新学科提供了动力，并经常在大众媒体上进行报道。

AST 0307668PI: ButlerOver the last 7 years roughly 100 extrasolar planets have been discovered, all from the precision Doppler velocity technique. The planets detected to date have profoundly challenged theories of planet formation and evolution, and motivated major space missions. The PI will continue this work in the southern hemisphere through the Anglo-Australian Planet Search program. This is the only southern hemisphere program to achieve the level of precision required for the detection of genuine "Solar System analogs", that is Jupiter and Saturn-mass planets beyond 4 astronomical units (the earth-Sun distance). With increased telescope access based on their successes the PI will increase their target list to include the 250 nearest and brightest southern hemisphere stars providing the first planetary census of nearby stars. This work has been credited with providing the motivation for the new disciplines of Astrobiology and extrasolar planet studies, and it is routinely reported in the popular press.
