Our principal con- clusions are: (1) the 8B neutrino flux is 1.3(1 ± 0.6) X 10~ neutrinos cm2 sec1 at Earth's surface if the uncertainties are assumed to combine like statistical errors; (2) the primordial helium mass fraction probably lies in the range 0.24-0.28; (3) the primordial heavy-element mass fraction probably lies in the range 0.018-0.036; (4) the fraction of energy generated by the CNO cycle is 0.03 ± 0.02; and (5) the luminosity of the Sun has increased by about 35 per cent in the last 4.7 billion years. We also present three numerical models for the solar interior and discuss some of their principal characteristics Publication: The Astrophysical Journal Pub Date: July 1968 DOI: 10.1086/149641 Bibcode: 1968ApJ...153..113B full text sources ADS |
