The internal properties of stars in the red-giant phase undergo significant changes on relatively short timescales. Long near-uninterrupted high-precision photometric timeseries observations from dedicated space missions such as CoRoT and Kepler have provided seismic inferences of the global and internal properties of a large number of evolved stars, including red giants. These inferences are confronted with predictions from theoretical models to improve our understanding of stellar structure and evolution. Our knowledge and understanding of red giants have indeed increased tremendously using these seismic inferences, and we anticipate that more information is still hidden in the data. Unraveling this will further improve our understanding of stellar evolution. This will also have significant impact on our knowledge of the Milky Way Galaxy as well as on exo-planet host stars. The latter is important for our understanding of the formation and structure of planetary systems.

巨星地震学

红巨星阶段恒星的内部特性在相对较短的时间尺度上发生显着变化。来自 CoRoT 和开普勒等专用太空任务的长期近乎不间断的高精度光度时间序列观测提供了对包括红巨星在内的大量演化恒星的全球和内部特性的地震推断。这些推论面临着理论模型的预测,以提高我们对恒星结构和演化的理解。通过这些地震推论,我们对红巨星的了解和了解确实大大增加了,我们预计数据中仍然隐藏着更多信息。解开这一点将进一步提高我们对恒星演化的理解。这也将对我们对银河系以及系外行星宿主恒星的了解产生重大影响。后者对于我们理解行星系统的形成和结构很重要。
