The chemical composition of the Sun from helioseismic and solar neutrino data

Understand

We perform a quantitative analysis of the solar composition problem by using a statistical approach that allows us to combine the information provided by helioseimic and solar neutrino data in an effective way.

• We include in our analysis the helioseismic determinations of the surface helium abundance and of the depth of the convective envelope, the measurements of the $^7{\rm Be}$ and $^8{\rm B}$ neutrino fluxes, the sound speed profile inferred from helioseismic frequencies.
• We provide all the ingredients to describe how these quantities depend on the solar surface composition and to evaluate the (correlated) uncertainties in solar model predictions.
• We include errors sources that are not traditionally considered such as those from inversion of helioseismic data.
