论文摘要
开普勒任务观察到数千名红色巨人。长时间的系列（只要任务本身）使我们能够以前所未有的细节研究红色巨人。鉴于红色巨人本质上是发光的，因此可以从非常大的距离观察到，知道红色巨人的特性，尤其是年龄，对于研究星系的形成和演变的研究是巨大的价值，银河系（一种被称为“银河考古学”的努力）。在本文中，我们回顾了使用Asteroseasic数据所学到的有关红色巨人的知识。我们从功率谱的特性开始，然后转向这些恒星的内部结构和动力学。我们还谈到了红色巨型星空学中未解决的问题，以及在理解这些恒星方面取得进一步进展的前景。
The Kepler mission observed many thousands of red giants. The long time series, some as long as the mission itself, have allowed us to study red giants with unprecedented detail. Given that red giants are intrinsically luminous, and hence can be observed from very large distances, knowing the properties of red giants, in particular ages, is of immense value for studies of the formation and evolution of the Galaxy, an endeavor known as "Galactic archaeology". In this article we review what we have learned about red giants using asteroseismic data. We start with the properties of the power spectrum and move on to internal structure and dynamics of these stars; we also touch upon unsolved issues in red-giant asteroseismology and the prospects of making further progress in understanding these stars.
