Condensation temperatures of C (top), O (middle), and S (bottom) in disks with varying compositions. Temperatures are plotted against molar C/O ratios of disks (left) and Σ/O, which is defined as the sum of all elements binding with oxygen, multiplied with their oxide stoichiometry, divided by the oxygen abundance, or Γ/O, where Γ = Σ – ϵ_C (right). The 50% condensation temperatures are shown as red dots, while effective condensation temperatures (see text) are shown as blue dots. Condensation temperatures are derived from condensation sequence calculations at P = 10⁻⁴ bar.
