太阳作为恒星演化的基本校准器

The Sun as a fundamental calibrator of stellar evolution

J. Christensen-Dalsgaard

摘要:

太阳在众多恒星中是独一无二的,它有一个精确确定的年龄,不依赖于恒星演化的模型。此外,太阳的其他整体性质比任何其他恒星都精确得多。此外,日震学提供了太阳内部结构和旋转的详细测定。因此,太阳在恒星模型的开发和测试中发挥着核心作用。在这里,我将讨论太阳模型及其应用于恒星年龄测定的星震技术测试。

英文摘要:

The Sun is unique amongst stars in having a precisely determined age which does not depend on the modelling of stellar evolution. Furthermore, other global properties of the Sun are known to much higher accuracy than for any other star. Also, helioseismology has provided detailed determination of the solar internal structure and rotation. As a result, the Sun plays a central role in the development and test of stellar modelling. Here I discuss solar modelling and its application to tests of asteroseismic techniques for stellar age determination.
