本文概述了恒星亮度振荡的可见度和暗化函数理论。为此，使用了非灰色近似，并探讨了不同类型恒星的不透明度扰动对恒星亮度振荡的影响。对南河三佯谬提出了一种解释。讨论了亮度振荡的特点。考虑了不透明度波动对p模振荡阻尼的影响。此外，还讨论了光球κ机制（© 2012 WILEY-VCH Verlag GmbH & Co. KGaA，魏因海姆）
In this paper the theory of visibility and darkening functions for the brightness oscillations of stars is outlined. For this the non‐grey approximation is used and the effect of opacity disturbances on stellar brightness oscillations is explored for different types of stars. An explanation of the Procyon paradox is proposed. Special features of the brightness oscillations are discussed. The effect of opacity fluctuations on the damping of p‐mode oscillations is considered. Furthermore, the photospheric kappa‐mechanism is discussed (© 2012 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
