The present helioseismic data, with their remarkable precision, provide the possibility to investigate the microscopic physics of the solar interior. In this study, we are specifically interested in the chemical composition and equation of state (EOS). Since these properties are not directly measurable, we chose the adiabatic gradient, γ1 ≡ ∂lnP/∂lnρ|s, as the probe to examine these properties. Specifically, we infer the discrepancies in the chemical composition and EOS by the discrepancy in γ1, i.e., δγ1/γ1, between two solar structures.
Even though the heavy elements only constitute less than 2% of the solar material, our inversion results showed that the variation in the relative abundances among heavy elements would result in discernible features in δγ1/γ1.
