Abstract
High sensitivity Doppier spectroscopy of integral sunlight in the 769.9 nm line of neutral potassium reveals several equally spaced lines of Q > 1,000 centred on the well known period of 5 min. These lines are interpreted as low l, high n overtones 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 workers1–3 have used spatial resolution to study the 5-min oscillation of the solar photosphere and have shown that power is concentrated along narrow ridges in the k, w diagram. These oscillations are mainly low n, high l value 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 low l value oscillations. These modes penetrate deeply5 and thus probe the structure as well as the interior angular velocity of the Sun6.
