Small adiabatic radial oscillations of composite stellar models are investigated in order to determine the effect of the central condensation rho(c)/rho-bar, where rho(c) is the density at the center and rho-bar is the mean density of the star, on the periods of pulsation. Results for the fundamental mode of the considered models along with others support the conclusion that rho(c)/rho-bar is not sufficient to characterize the effect of the density distribution on the periods. The second moment of mass concentration was calculated, and it is found that the periods of all the models monotonically increase with increase of the second moment of the mass concentration. Thus, the latter characterizes the periods more effectively than the central condensation. The amplitudes are found to increase more rapidly than the core.
