Abstract
The discovery of radial and non-radial global oscillations of the Sun through various types of detector systems has opened the field of solar seismology. Of particular importance for studies of the deep interior of stars are the detection and analysis of low harmonic order pulsations such as the low order p-modes recently found on the Sun1,2 by line shift measurements. These pulsations have now also been detected in the solar brightness fluctuations. Through the reflected light of Uranus and Neptune the Sun was observed as though it were a distant star. The positive results suggest that broad-band photometry has the greatest potential for developing seismometry of main sequence stars.
