Octave（伯明翰-谢菲尔德哈勒姆）用于提取类太阳主序星振荡参数的自动管道
The Octave (Birmingham - Sheffield Hallam) automated pipeline for extracting oscillation parameters of solar-like main-sequence stars
摘要：
随着美国航天局开普勒卫星的短节奏高精度光度观测，我们可以观测到类似太阳振荡的主序星数量预计将大大增加。由于恒星数量的增加，需要自动化工具在合理的时间内分析这些数据。在asteroFLAG联盟的框架内，我们提出了一个自动化的管道，提取主序星和次巨星中的类太阳振荡的频率和其他参数。管道仅使用时间序列数据作为输入，不需要任何其他输入信息。对353颗人造恒星的测试表明，我们可以获得大约四分之三的恒星的准确频率和振荡参数。我们的结论是，我们的方法是非常适合的主序星，主要表现出p-模式振荡的分析。
英文摘要：
The number of main-sequence stars for which we can observe solar-like oscillations is expected to increase considerably with the short-cadence high-precision photometric observations from the NASA Kepler satellite. Because of this increase in number of stars, automated tools are needed to analyse these data in a reasonable amount of time. In the framework of the asteroFLAG consortium, we present an automated pipeline which extracts frequencies and other parameters of solar-like oscillations in main-sequence and subgiant stars. The pipeline uses only the timeseries data as input and does not require any other input information. Tests on 353 artificial stars reveal that we can obtain accurate frequencies and oscillation parameters for about three quarters of the stars. We conclude that our methods are well suited for the analysis of main-sequence stars, which show mainly p-mode oscillations.
