Left: mean T_cond slope (﹩\frac{\partial [{\rm{X}}/{\rm{Fe}}]}{\partial {T}_{{\rm{cond}}}}﹩) as a function of mean [α/Fe] and colored by mean [Fe/H] with uncertainties on the mean for solar analogs with B18 as circles, GALAH as squares, R24 as diamonds, and APOGEE as stars. There is a positive gradient in T_cond slope with [α/Fe] (10 ± 4E-4 K⁻¹) and a similarly strong negative gradient with [Fe/H] as well (-4 ± 1E-4 K⁻¹). Metal-rich, α-enriched stars tend to have ﹩\frac{\partial [{\rm{X}}/{\rm{Fe}}]}{\partial {T}_{{\rm{cond}}}}﹩ = 0, consistent with the Sun. The APOGEE stars are systematically offset from the rest of the surveys, given their difference in kinematic selection. Right: [Fe/H]–[α/Fe] distribution of stars colored by their T_cond slope. We confirm what was seen on the left panel: the majority of stars with a T_cond slope consistent with zero are metal-rich and depleted in [α/Fe] compared to the Sun. Hexbin cells with mean T_cond slopes consistent with zero are centered at [Fe/H] = 0.1 dex and [α/Fe] = −0.02 dex.
