Correlation between the C/O ratio and the condensation temperature of some major planet-building elements, corrected for the metallicity 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.
