differential rotation



  1. The variable rotation rate of a gassy body, such as a star or gas giant planet, with latitude; gas near the equator spins around faster than gas near the poles.

  2. The variable rotation in a disk-shaped structure, such as a galaxy, according to distance from its center. Stars near the center take less time to complete one rotation than those further away.
