Observed [X/Mg]–[Mg/Fe] for Cr, Si, and Al for solar analogs with uncertainties <0.03 dex, shown in order of their T_cond and colored by their observed T_cond slope. Low-T_cond elements like Cr show declining [X/Mg] with [Mg/H], while high-T_cond elements like Al track Mg more closely, resulting in flatter trends. This progressive flattening with increasing T_cond suggests that T_cond correlates with stellar yields and reflects systematic differences in nucleosynthetic origin and the relative contributions from core-collapse and Type Ia supernovae. Data are not separated by survey here for visual clarity.
