Helioseismology, solar models and neutrino fluxes.
Abstract
The authors present results concerning a systematical analysis of helioseismic implications on solar structure and neutrino production. They find Yph = 0.238 - 0.259, Rb/Rsun = 0.708 - 0.714 and ρb = (0.185 - 0.199) gr/cm3. In the interval 0.2 < R/Rsun < 0.65, the quantity U = P/ρ is determined with an accuracy of ±5o/oo or better. At the solar center still one has remarkable accuracy, ΔU/U < 4%. The authors compare the predictions of recent solar models (standard and non-standard) with the helioseismic results. By constructing helioseismically constrained solar models, the central solar temperature is found to be T = 1.58×107K with a conservatively estimated accuracy of 1.4%, so that the major uncertainty on neutrino fluxes is due to nuclear cross section and not to solar inputs.
