Density and temperature as a function of radius for the atmosphere around an 0.1 M_⊕ core at several snapshots during the dynamic outflow caused by a drop of the density at the outer boundary from 5 × 10^-10 g/cm³ to 5 × 10^-25 g/cm³ over ≃32 yr. The dash-dotted lines are the initial model, and after the dynamic outflow phase the configuration again settles in a hydrostatic configuration indicated by dashed lines. The times of the snapshot are, from top to bottom, in yr: 0 (dash-dotted line), 3.9, 7.5, 9, 11, 13, 17, 64, 141, 148, 154, ∞ (dashed line). In the color version of this figure, some lines are highlighted in color to simplify the identification of equivalent snapshots in the two panels.
