  The recently formulated model of black holes coupled to the radial flows of
dark matter (RDM-stars) is considered and the shape of the galactic rotation
curves predicted by the model is evaluated. Under the assumption that the
density of black holes is proportional to the density of luminous matter, the
model perfectly fits the experimental data, both for the universal rotation
curve, describing the spiral galaxies of a general form, and for the grand
rotation curve, describing the orbital velocities of Milky Way galaxy in a wide
range of distances. The modeling of the galactic gravitational field at large
distances from the center and out of the galactic plane is also discussed.
