A Non-magnetic Solution...

  • A solution to the impermeability of the tachocline may be possible with only hydrodynamic flows.

  • Differential rotation maintained across tachocline, except at tachopause

  • Assume anisotropic turbulence. (Is this unphysical?)

  • Certain configurations of 2-D instability across shells can induce radial stability in simulations.

  • Highly dependent on viscosity/Reynolds number, which is not well known deep in the interior.
