中性钾 769.9 nm 线中积分太阳光的高灵敏度多普勒光谱揭示了以众所周知的 5 分钟周期为中心的几条等距的 Q> 1,000 线。这些线被解释为整个太阳的低、高中频，如果从当前的太阳模型来看，似乎意味着低重元素丰度和随之而来的低太阳中微子通量。之前的工作人员 1-3 已经使用空间分辨率来研究太阳光球层的 5 分钟振荡，并表明功率集中在图中的狭窄山脊上。这些振荡主要是整个太阳的低值、高值声学模式。与此相反，目前的工作（摘要参见参考文献 4）旨在全面了解太阳表面，因此偏向于低值振荡的研究。这些模式深入穿透5，从而探测太阳的结构以及内部角速度6。
High sensitivity Doppier spectroscopy of integral sunlight in the 769.9 nm line of neutral potassium reveals several equally spaced lines ofQ> 1,000 centred on the well known period of 5 min. These lines are interpreted as lowl, highnovertones of the entire Sun and, if viewed in terms of current solar models, appear to imply a low heavy element abundance and a consequent low solar neutrino flux. Previous workers1–3have used spatial resolution to study the 5-min oscillation of the solar photosphere and have shown that power is concentrated along narrow ridges in thek,wdiagram. These oscillations are mainly lown, highlvalue acoustic modes of the entire Sun. In contrast to this, the present work (for a summary see ref. 4) is aimed at an overall view of the solar surface and consequently is biased to a study of lowlvalue oscillations. These modes penetrate deeply5and thus probe the structure as well as the interior angular velocity of the Sun6.
