Radial differential rotation vs surface differential rotation: investigation based on dynamo models
H. Korhonen & D. Elstner

Abstract

Differential rotation plays a crucial role in the alpha-omega dynamo, and thus also in the creation of magnetic fields in stars with convective outer envelopes. Still, measuring the radial differential rotation on other stars than the Sun is impossible with the current instruments and observing techniques, and even the measurement of surface differential rotation is difficult. In this work we investigate the surface differential rotation obtained from dynamo models using similar techniques as are used on observations, and compare the results with the known radial differential rotation used when creating the Dynamo model.
