Scientific paper

Observations of solar oscillations made over a period of five years are reviewed, and implications of the observations for the physics of the solar interior are indicated. An analysis of over 1000 hours of solar observations from 1974 to 1978 is presented which shows the observed oscillations of the solar radius to be real, with a period of 160.010 + or - 0.004 min and a Doppler shift amplitude of 1 m/sec. The slow drift of the phase of the velocity maximum has been observed, together with the dependence of the amplitude on the phase of the solar rotation period. Synchronous oscillations of the solar magnetic field and radio emission have also been found to be synchronous to the brightness oscillations, and the oscillations have been seen to disappear occasionally, possibly due to the passage of a supergranule across the solar disk. It is suggested that the oscillations represent gravitational quadrupole oscillations, and could serve as a means for nonradiative heat transfer from within the sun and thus alleviate the problem of low neutrino flux.
