On the seismic age of the Sun

Abstract

We use low-degree acoustic modes obtained by the BiSON to estimate the main-sequence age tt_\odot of the Sun. The calibration is accomplished by linearizing the deviations from a standard solar model the seismic frequencies of which are close to those of the Sun. Formally, we obtain the preliminary value t=4.68±0.02t_\odot=4.68\pm0.02 Gy, coupled with an initial heavy-element abundance Z=0.0169±0.0005Z=0.0169\pm0.0005. The quoted standard errors, which are not independent, are upper bounds implied under the assumption that the standard errors in the observed frequencies are independent.
