Helioseismology and p+p → d + e+ + νe in the sun

By using a phenomenological field theory of nucleon-nucleon interactions, Oberhummer et al. found a cross section of p+p → d + e+ + νe about 2.9 times that given by the potential approach and adopted in Standard Solar Model calculations. We show that a solar model with S=2.9SSSM is inconsistent with helioseismic data, the difference between model predictions and helioseismic determinations being typically a factor ten larger than estimated uncertainties. We also show that, according to helioseismology, S cannot differ from SSSM by more than 15%.
