Local Mixing near the Solar Core, Neutrino Fluxes and Helioseismology

Abstract

We have computed solar models similar to those published in Richard, Vauclair, Charbonnel, Dziembowski (1996), in which we have added local mixing near the solar core in order to decrease the neutrino production. The results show that the neutrino fluxes are reduced as expected (although not enough to account for the observed values), but the obtained models are incompatible with the inversion of the helioseismic modes. We have specially tested the parametrized mixing proposed by Morel and Schatzman (1996). The resulting solar models are far from the seismic model and thus unrealistic.
