Correlation between element ratios and the condensation temperatures, corrected for the metallicity and C/O effect. The coloured circles in the foreground show the simulation results of the synthetic abundance patterns, and the grey circles in the background show the simulation results of a representative subset of approximately 100 stars from the Brewer et al. (2016) database. All simulations were run at a constant disk pressure of p = 10⁻⁴ bar. Left panel: influence of the Al/Ca ratio on the condensation temperature of Al and Ca. Right panel: influence of the Mg/Si ratio on the condensation temperature of Mg and Si.
