The sensitivity of the seismic solar model to Newton's constant

摘要: New experimental determinations of Newton’s gravitational constant have been recently given. There are significant disagreements between these new measurements. We show that the high accuracy obtained with current standard solar models is such uncertainties in core temperature profiles arising from G can be comparable to range predictions by model observed acoustic modes and neutrino fluxes. Solar computed a relatively value constant, agreement measurements, produce an increase predicted sound speed density profiles, changes structure within central region. These predict active 8 B flux slightly closer Sudbury Neutrino Observatory Super-Kamiokande measurements than previous (with CODATA 1986). Furthermore, we find 6.65 × 10 −8 6.685 cm 3 g −1 s −2 will reasonable seismic model. Current physics opacities prevent any stronger conclusions at present. However, may able potentially use Sun determine independent representing alternative measurement determined Earth laboratories.
