Scientific paper

Measurements of the rotation velocities and macroturbulence dispersions in the four Hyades K giants are presented. The observed rotation is approximately 40% of that expected from evolutionary models in which convective envelopes are assumed to rotate as rigid bodies. It is possible to explain this discrepancy either by postulating that a magnetic braking has occurred or that the coupling is not strong enough to maintain rigid-body rotation in convective layers. Evolutionary models having uniform specific angular momentum in the convective layers are constructed and found to agree with the observed rotation rates.
