Query: Radial differential rotation vs surface differential rotation:
  investigation based on dynamo models   Differential rotation plays a crucial role in the alpha-omega dynamo, and
thus also in creation of magnetic fields in stars with convective outer
envelopes. Still, measuring the radial differential rotation on stars is
impossible with the current 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.
