Scientific paper

We revisit the problem of pulsational stability of radial and strongly trapped non-radial modes of red giant stars. We present the results of numerical computations of oscillation properties of a 2.03 Msolar evolutionary stellar model along the AGB. We examine the pulsational stability by taking into account the effect of perturbation of convective flux during the pulsation. Results obtained by using the standard ``frozen'' convection are presented for comparison.
