Abstract: Solar models calibrated using the AGS05 solar abundance mixture do not produce as good agreement with oscillation frequencies or helioseismic inferences of sound speed, convection zone depth, or convection zone helium abundance compared to models using the older GS98 or GN93 abundances. Here we summarize attempts to date to mitigate this problem, and show the effects of including low-Z accretion or convective overshooting as examples. We find that including more elements in the mixture used to generate Rosseland mean opacities has a negligible effect on these opacities for solar interior temperatures and densities, so will not provide a solution to this problem.
