Fig. 3.

Chemical abundances of a gas mixture after dilution of a solar-composition gas with abundances from Fig. 2. Left panel: composition after dilution by a factor of two. Middle panel: the gas is diluted by a factor of 100. Finally, in the right panel: the gas is diluted by a factor of 10 000, to the point where we retrieve the initial accretion abundances from Fig. 2.
