Scientific paper

The properties of the nonlinear pulsations of the yellow supergiant stars in the post-AGB stage are examined by using hydrodynamic simulations. It is shown that irregular oscillation with small amplitudes is yielded in radial pulsation of hydrodynamic models for yellow supergiant stars in the postasymptotic giant branch. In nonlinear hydrodynamic simulations, subharmonic components are strongly enhanced in the nonlinear pulsations in the chaotic regime, so the nonlinear pulsation can yield much longer time-scale variations.
