A SEISMIC SOLAR MODEL WITH THE UPDATED ELEMENTAL ABUNDANCES

摘要

It has been stressed that the improved measurement of the solar elemental abundances makes the discrepancies between the helioseismically determined sound speed profile and the evolutionary model of the sun significantly larger. We demonstrate that one can construct a seismic model of the sun at the present day with constraints of the helioseismically determined sound speed and the new abundances, but without following the evolution of the sun, so that the model is consistent with both helioseismology and the new abundances. The 8{sup left}B neutrino flux estimated from this model is, however, about only 60% of the experimental data measured by the SNO neutral-current mode and as small as the measured electron neutrino flux without correction due to the neutrino oscillation.
