Abstract

We show that helioseismology provides information oil Beryllium neutrino production in the Sun. ill particular, we derive a lower limit oil the Beryllium neutrino flux on earth. Phi (min)(Be) = 1 . 10(9)cm(-2)s(-1), in the absence of oscillations. by using helioseismic data, the B-neutrino flux measured by Superkamiokande and the hydrogen abundance at the solar center predicted by Standard Solar Models. Moreover. we obtain an helioseismic determination of Phi (Be) by comparing solar model with artificially changed v(Bc) production with helioseismic data.
