The three-dimensional gas dynamic model of the gravitating protoplanet disk, rotating around the gravitating center is investigated. The numerical algorithm for finding the steady flows in the disk, which uses a solution of the system of nonlinear equations, is built. Density, mass and gravitational potential increase several times in comparison with the model, which does not consider gravity of disk. The parameter Toomre, which determines the stability of steady-state solution, is calculated.
Keywords: gravitational instability, proto-planet disk, parameter of the stability.
