Abstract
Two implications of the recent observations1 of low angular, high radial overtones of the whole Sun are reported here. 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 Y≲0.17 with implications for cosmological models.
