Abstract

Several properties of the solar interior are determined with a very high accuracy, which in some cases is comparable to that achieved in the determination of the Newton constant G(N). We find that the present uncertainty DeltaG(N)/G(N) = +/-1.5 x 10(-3) has significant effects on the profile of density and pressure, however, it has negligible influence on the solar properties which can be measured by means of helioseismology and B-8 neutrinos. Our results do not support recent claims that observational solar data can be used to determine the value of GN with an accuracy of few part in 10(-4). Present data cannot constrain GN to much better than 10(-2). (C) 2002 Elsevier Science B.V. All rights reserved.
