What is the most like the rotation of stars in the disk of the milky way?

The rotation of stars in the disk of the Milky Way resembles that of a rotating carousel, where stars closer to the center orbit faster than those farther out. This differential rotation results in a spiral structure, with stars in the inner regions completing their orbits in a shorter time compared to those in the outer regions. The overall rotation curve of the galaxy, however, remains relatively flat beyond a certain radius, indicating the presence of dark matter influencing the motion of stars.
