Evolution of the Rosseland mean opacity in the inner helium envelope (υ = 4700 km s−1) for the macroscopically mixed model with strong expansion (black) and the corresponding Rosseland mean opacity in the limits of optically thick (blue) and thin (red) clumps. In addition, we show the evolution of the Rosseland mean opacity for the macroscopically mixed model without expansion (cyan).
