标题： Ensemble asteroseismology of red-giant stars

摘要： 成功发射CoRoT和Kepler空间任务导致在大量红巨星恒星中检测到类似太阳的振荡。 观测到振荡的红巨星数量庞大，使得可以研究整个样本的特性：集合星震学。 在本文中，我们总结了由Kepler科学团队发布的数据（约150,000个场星）得到的集合星震学结果，如Hekker等人（2011b）所展示，并针对NGC 6791、NGC 6811和NGC 6819星团（Hekker等人，2011a）进行讨论，并我们讨论了此类研究的重要性。 显示英文摘要

摘要： The successful launches of the CoRoT and Kepler space missions have led to the detections of solar-like oscillations in large samples of red-giant stars. The large numbers of red giants with observed oscillations make it possible to investigate the properties of the sample as a whole: ensemble asteroseismology. In this article we summarise ensemble asteroseismology results obtained from data released by the Kepler Science Team (~150,000 field stars) as presented by Hekker et al. (2011b) and for the clusters NGC 6791, NGC 6811 and NGC 6819 (Hekker et al. 2011a) and we discuss the importance of such studies.
