Abstract: (Elsevier)
We discuss what appears the last hope for an astrophysical solution to the solar neutrino problem: a correlated variation of the astrophysical factors for the helium burning cross sections ( S 33 and S 34 ) and either S 17 or the central temperature T c . In this context, we recognize the important role played by the CNO neutrinos. In fact, we can obtain a fair fit to the experimental data only if three conditions are met simultaneously: the astrophysical factor S 33 is about 200 times what is presently estimated, the astrophysical factor S 17 is about 3 times larger and the 13 N and 15 O neutrino fluxes are negligible compared to the ones predicted by standard solar models. These conditions are not supported by the present data and their correlated combination is improbable.
