Effect of disk thickness on the morphology of spiral structure excited by a recent stellar encounter. The top panels show a simulation with disk aspect ratios ﹩h/ r=0.04﹩ (simulation S) compared with that with ﹩h/ r=0.10﹩ (simulation U), which is shown in the bottom panels. Left to right, each panel corresponds to a different time after the closest approach (with times the same as those in Fig. 8). For these simulations, the mass ratios ﹩q=0.1﹩. Thicker disks exhibit lower amplitude and less long lived prominent spiral structure following a flyby.
