摘要

The non-radial oscillations discovered by CoRoT (see e.g. de Ridder et al. (2009)) and by Kepler (see e.g. Bedding et al. (2010)) in thousands of red giants constitute a wonderful mine of information to determine their global characteristics and probe their internal structure. A. Miglio and J. Montalban have presented in detail in this conference the seismic structure of red giants, the information hold by their oscillation frequencies, and how it can be used. An adiabatic analysis of the oscillations was sufficient at this level as the frequencies are mainly determined by the deep layers were the oscillatons are quasi-adiabatic. We consider here energetic aspects of non-radial oscillations in red-giants. Non-adiabatic models of solar-like oscillations are required to determine the theoretical amplitude and lifetimes of the modes. These parameters allow us to determine how power spectra are expected to look like, depending on the structure of the red giant. Comparison with the observed measures gives thus additional constraints on the models.

Montalban在会议上详细介绍了红巨星的地震结构，其振荡频率所掌握的信息以及如何使用它。在此水平上对振动进行绝热分析就足够了，因为频率主要由深层决定，而振荡是准绝热的。我们在这里考虑红巨人的非径向振荡的能量方面。需要类似太阳的振荡的非绝热模型来确定模式的理论幅度和寿命。这些参数使我们能够确定功率谱的外观，具体取决于红色巨人的结构。因此，与观察到的测量值进行比较会给模型带来额外的约束。
