HD 189733b’s calculated cloud structure at the sub-stellar point (θ = 0°, φ = 0°). Left: 1st panel: local gas temperature Tgas [K] (solid, left) and mixing timescale τmix [s] (dashed, right). 2nd panel: nucleation rate J [cm-3s-1] (solid, left) and dust number density nd [cm-3] (dashed, right). 3rd panel: growth velocity of material sχ [cm s-1]. 4th panel: volume fraction Vs/Vtot of solid s. 5th panel: effective supersaturation ratio Seff of individual solids. 6th panel: cloud particle mean radius a [μm] (solid, left) and mean drift velocity vdr [cm s-1] (dashed, right). Right: key showing line-style and colour of our considered dust species.
