Scientific paper

Two implications of the recent observations (Claverie et al., 1979) of low angular, high radial overtones of the whole sun are reported. The first implication is that other main sequence stars are likely to be oscillating in similar modes and that precision spectroscopy as well as photometry from space is capable of detecting these oscillations, thereby extending seismology to stars. The second implication is a solar helium abundance less than approximately 0.17, with implications for cosmological models.
