Effect of a complex C-dominated atmosphere on a selection of vaporised species: The partial pressures of the selected vaporised species (O₂, SiO, TiO, Fe, Na, and K) in a complex (including C, H, N, and S) C-dominated volatile atmosphere are shown using solid lines, while the dashed lines are used to indicate their partial pressures in volatile free atmospheres. The left panel (a) shows the partial pressures as a function of total volatile pressure at a fixed surface temperature of 3000 K. The right panel (b) shows the partial pressures as a function of surface temperature at a fixed total volatile pressure of 1 bar.
