In this paper, we determine the dynamic viscosity for the case of pulsating disturbances in the density of gas-dust disks. The characteristic velocities of the disk dust particles are divided into separate classes of orbits with Keplerian and near-Keplerian motions. For these classes, we obtain formulas for the dynamic viscosity. We analyze the distributions of exoplanets by their masses, major semi-axes, and eccentricities of their orbits. We conclude that hot giant planets can be located on complex, unstable orbits of accretion onto the central star.
