| Abstract: | Gasdynamic features of detached shells around carbon stars with variable mass loss rate are investigated in detail numerically.
It is shown that a shell is unstable and also, 2D perturbations are less developed that 3D ones. The structure of perturbed
flows corresponding to different evolution scenarios is compared. The results obtained seem to be promising for interpretation
of observations, in particular, the recently obtained detailed data of TT Cyg.
