恒星流体动力学:用CoRoT和开普勒进行的天文地震学

Stellar hydrodynamics caught in the act: Asteroseismology with CoRoT and Kepler

Jorgen Christensen-Dalsgaard, Michael J. Thompson

摘要:

天文地震研究,特别是基于CoRoT和开普勒空间飞行任务的恒星振荡数据,为研究恒星内部的性质提供了独特的可能性。这构成了研究动力学现象对恒星结构和演化影响的全新方法。重要的例子是对流区的范围和相关的混合以及恒星旋转的直接和间接影响。此外,恒星振荡本身也表现出非常有趣的动力学行为。在这里,我们讨论的例子,从这样的调查中获得的结果,在赫兹-罗素图。

英文摘要:

Asteroseismic investigations, particularly based on data on stellar oscillations from the CoRoT and Kepler space missions, are providing unique possibilities for investigating the properties of stellar interiors. This constitutes entirely new ways to study the effects of dynamic phenomena on stellar structure and evolution. Important examples are the extent of convection zones and the associated mixing and the direct and indirect effects of stellar rotation. In addition, the stellar oscillations themselves show very interesting dynamic behaviour. Here we discuss examples of the results obtained from such investigations, across the Hertzsprung-Russell diagram.
