Abstract

This paper focuses mainly on the neutrino puzzle and discusses the point of view that neutrinos and helioseismology are two complementary probes of the solar interior. We first analyze the physical differences noticed between already published solar models and their consequences for neutrino predictions. We propose new results on the solar neutrino predictions and acoustic mode frequencies for l = 0-150, in the classical framework of stellar evolution. We quantify the influence of precise composition, nuclear reaction rates, screening effect, and opacity calculations on both neutrino and acoustic mode frequency predictions. Our present predictions are 6.4 +/- 1.4 SNU for the chlorine experiment, 4.4 +/- 1.1 x 10 exp 6/sq cm/s for the water detector, and 122.5 +/- 7 SNU for the gallium detector.
