Radial profiles of chemical and dust-related quantities. The temperature of the SPH gas, with which the dust is assumed to be fully thermalised, is shown in red. Left: the logarithm of the third moment 𝒦3 (blue), which represents the number density of condensing monomers from the gas phase into the dust, shown together with the dust opacity profile (green). Right: the mean molecular weight μ (blue), polytropic index γ (green), and the base 10 logarithm of the supersaturation ratio S (magenta) of the gas in the wind. A supersaturation ratio above unity implies favourable conditions for dust formation.
