Solar neutrinos and the solar composition problem

Pena-Garay, Carlos, Serenelli, Aldo

Understand

Standard solar models (SSM) are facing nowadays a new puzzle: the solar composition problem.

New determinations of solar metal abundances lead SSM calculations to conflict with helioseismological measurements, showing discrepancies that extend from the convection zone to the solar core and can not be easily assigned to deficiencies in the modelling of the solar convection zone.
We present updated solar neutrino fluxes and uncertainties for two SSM with high (old) and low (new) solar metallicity determinations.
The uncertainties in iron and carbon abundances are the largest contribution to the uncertainties of the solar neutrino fluxes.
