Temporal evolution of a DARWIN model with input parameters M_* = 1 M_⊙, log L_* ∕L_⊙ = 4.00, T_* = 2600 K, u_p = 6 km s⁻¹, log (C- O) + 12 = 8.5, and [Fe∕H] = −1.0 (SMC). Thepanels show luminosity and the resulting mass-loss rate at the outer boundary. The wind properties for this model are calculated by averaging over the time interval marked in black. The two embedded panels show the snapshots selected for the a posteriori radiative transfer in red.
