Book excerpt: Thanks to helioseismology we know the internal rotation of the Sun as a function of radius and latitude. The presence of a shear at the base of the solar convection zone is thought to play a key role in the generation of magnetic fields. So far however, the internal rotation profiles of stars other than the Sun are unknown, and placing constraints on models of rotation and magnetic dynamos is therefore difficult.. The NASA Kepler mission has provided high-quality photometric data that can be used to study the rotation of stars with two different techniques; asteroseismology and surface acti...
