Ensemble asteroseismology of red-giant stars

S. Hekker, R. L. Gilliland, Sarbani Basu, J. De Ridder, W. J. Chaplin, Y. Elsworth

摘要:

CoRoT和开普勒太空任务的成功发射,导致在大量红巨星样本中探测到类似太阳的振荡。大量的红巨星与观测到的振荡使得有可能调查的性质的样本作为一个整体:合奏天文地震学。在这篇文章中,我们总结了Hekker等人(2011 b)和NGC 6791,NGC 6811和NGC 6819星团(Hekker等人2011 a)从开普勒科学小组(约150,000颗场星)发布的数据中获得的集合星震学结果,我们讨论了这些研究的重要性。

英文摘要:

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.
