Multi-epoch snapshots of the density (top), temperature (middle), and velocity vs. Lagrangian mass for model He_R173 (solid). For the top two panels, we include the results for model He_R11 (dashed). Bottom panel: different epochs and only the outer envelope. The time origin corresponds to the piston trigger (the piston mass cut is located at 1.4 M⊙). A reverse shock forms after ~20 min in the model with the extended low-density envelope. This reverse shock leads to the formation of a dense shell of 0.2 M⊙ at m = 2.4 M⊙. For better visibility, all profiles in the top two panels are shifted vertically by a constant.
