Low-metal core solar models with helioseismic constraints and the solar neutrino problem

With the imposition of the seismically determined sound speed profile, we construct solar models having low metal abundance in the core and evaluate the neutrino fluxes of these models to see if nonstandard solar models with a low metal core can solve the solar neutrino problem. Some of these models are in agreement with the Homestake and the Super-Kamiokande data, but none of these satisfy simultaneously all the neutrino flux data including GALLEX and SAGE and the helioseismically inverted density profile.
