近地表效应与太阳年龄测定

Near-surface effects and solar-age determination

G. Doğan, A. Bonanno, J. Christensen-Dalsgaard

摘要:

太阳的观测频率和模型频率之间的差异的主要部分可以近似为幂律。结果表明,当用这一经验定律校正模型频率,再用小频率间隔测定太阳年龄时,所得结果与陨石年龄(4.563 Gyr < t < 4.576 Gyr)一致。我们提出的结果,并与那些通过使用小到大的频率分离的比率得到的比较。

英文摘要:

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.
