(a) Response of the gas disk upon applying a transient leading spiral perturbation in the ﹩Q_{g}=1.3﹩ disk. Times are given in machine units (at ﹩\xi =1﹩, one full revolution requires ﹩t=39.2﹩). (b) Response of the gas disk upon applying a transient leading spiral perturbation in the ﹩Q_{g}=2.48﹩ disk.
