Turbulent viscosity in a gravitating gaseous disk

Journal Article · · Sov. Astron. Lett. (Engl. Transl.); (United States)
OSTI ID:5171620
If a gaseous, gravitationally stable disk contains a region which is only marginally stable, an anomalously high turbulent viscosity coefficient ..nu../sub T/ will develop, exceeding the molecular kinematic viscosity coefficient ..nu.. by a factor of at least (h/l)/sup 2/3/. Lower limits are placed on the parameter ..cap alpha..equivalent..nu../sub T//c/sub s/h in the theory of accretion disks having a self-gravitating peripheral zone: ..cap alpha../sub min/approx.(l/h)/sup 1/3/ if L>L/sub 0/ and ..cap alpha../sub min/approx.lL/sup 2//h/sup 3/ if L
