On the Dynamical Foundations of Alpha Disks
- Abstract:
-
The dynamical foundations of $\alpha$ disk models are described. At the heart of the viscous formalism of accretion disk models are correlations in the fluctuating components of the disk velocity, magnetic field, and gravitational potential. We relate these correlations to the large scale mean flow dynamics used in phenomenological viscous disk models. MHD turbulence readily lends itself to the $\alpha$ formalsim, but transport by self-gravity does not. Nonlocal transport is an intrinsic prop...
