Abstract Theory of the ablative Richtmyer-Meshkov instability is presented. It is shown that the main stabilizing mechanism of the ablation-front perturbations during the shock transit time is the dynamic overpressure that causes perturbation oscillations. The amplitude of the oscillation is proportional to c{sub s}/{radical}(V{sub a}V{sub bl}) and its frequency is {omega}=k{radical}(V{sub a}V{sub bl}) , where k is the wave number, and c{sub s} , V{sub a} , and V{sub bl} are sound speed, ablation, and blow-off plasma velocities, respectively. {copyright} {ital 1999} {ital The American Physical Society}
