Solar models of low neutrino counting rate: energy transport by processes other than radiative transfer.
Abstract
A sequence of solar models is presented in which decreasing fractions of the energy flux are carried by radiation. It is found that counting rates below 1 SNU can be obtained for Cl-37 observations if more than half of the solar energy is transported to the convective layers by nonradiative means. It is shown that the low-SNU models have very low central temperatures, require extremely helium-poor compositions, and are unable to penetrate below Ulrich's (1974) theoretical limit of 0.5 SNU, a characteristic shared by all models in which nuclear reactions provide all the power. Energy transport by acoustic waves is mentioned as a possible, if somewhat unpromising, candidate for a nonradiative mechanism.
