Revisiting the standard solar model

The authors investigate the mutual consistency between contemporary standard solar models, based on the recent Los Alamos opacity tables. Satisfactory agreement is found among these models concerning the helium content and the neutrino capture rates, considering the extreme sensitivity of the <SUP>8</SUP>B neutrino flux to central conditions of the Sun. The authors' reference model leads to a solar helium content of 0.276±0.012 by mass fraction, a capture rate of 5.8±1.3 SNU on <SUP>37</SUP>Cl and 125±5 SNU on <SUP>71</SUP>Ga.
