The Anglo-Australian Planet Search

在过去的7年里，大约有100颗系外行星被发现，都是通过精确的多普勒速度技术发现的。迄今为止探测到的行星深刻地挑战了行星形成和演化的理论，并激发了重大的太空任务。PI将通过英澳行星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“太阳系类似物”所需的精度水平的计划，即木星和土星质量的行星超过4个天文单位（地球-太阳距离）。在他们成功的基础上，随着越来越多的望远镜进入，PI将增加他们的目标名单，包括250颗最近的、最亮的南半球恒星，为附近的恒星提供第一次行星普查。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，并在大众媒体上定期报道。

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.
