Abstract
We show that helioseismology provides information on Beryllium neutrino production in the Sun. In particular, we derive a lower limit on the Beryllium neutrino flux on earth, ΦminBe = 1 · 109 cm-2s-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 ΦBe by comparing solar model with artificially changed νBe production with helioseismic data. © 2001 Elsevier Science B.V.File in questo prodotto:
