Near-surface effects and solar-age determination
arXiv:1004.2215
Abstract
The dominant part of the difference between the observed and model frequencies of the Sun can be approximated by a power law. We show that when this empirical law is employed to correct the model frequencies and then the small frequency separations are used for solar age determination, the results are consistent with the meteoritic age (4.563 Gyr < t < 4.576 Gyr). We present the results and compare with those obtained by using the ratios of small to large frequency separations.
