Influence of the density at the lower boundary on the mass-loss rates. The density a) and the temperature b) in the lower atmosphere of HD 209458 b are depicted. The insert shows the density structures shifted to merge the profiles. Panel c) shows the change in the mass-loss rate in the two test simulations (HD 209458 b, HD 189733 b). The color scheme indicates the boundary density ranging from 1015 cm-3 (dark blue) to 1012 cm-3 (green). Reducing the boundary density by two orders of magnitude decreases the mass-loss rate by less than 40%.
