The influence of angular momentum transport by turbulent friction on the structure of a rotating protostar has been investigated. Turbulence is characterized by a simple viscosity parameter η = ξ·cs·1, where cs denotes the local speed of sound, 1 the typical length scale of the largest eddies (thickness of the nebula) and ξ the “efficiency” parameter (= 1/10 in our model).
