Stellar Metamorphosis: Differential Rotation in Stars

Authors: Jeffrey Joseph Wolynski

Differential rotation is when a portion of a star rotates faster than another. With young stars like the Sun, this is more pronounced, with the equatorial angular velocity being higher than the polar angular velocity. The angular velocity remains differential between the poles and equator when the star is young, and then equalizes as the star evolves. This means the oldest stars will not have differential rotation (as well as no global magnetic activity), and the youngest will have the most pronounced. Explanation is provided.
