Memory effects in turbulent transport
Alexander Hubbard, Axel Brandenburg
In the mean-field theory of magnetic fields, turbulent transport, i.e. the turbulent electromotive force, is described by a combination of the alpha effect and turbulent magnetic d…
Identifying Deficiencies of Standard Accretion Disk Theory: Lessons from a Mean-Field Approach
Alexander Hubbard, Eric G. Blackman
Turbulent viscosity is frequently used in accretion disk theory to replace the microphysical viscosity in order to accomodate the observational need for in- stabilities in disks th…
AGN Jet Mass Loading and Truncation by Stellar Winds
Alexander Hubbard, Eric G. Blackman
Active Galactic Nuclei can produce extremely powerful jets. While tightly collimated, the scale of these jets and the stellar density at galactic centers implies that there will be…
Planetesimal growth in turbulent discs before the onset of gravitational instability
Alexander Hubbard, Eric G. Blackman
It is difficult to imagine a planet formation model that does not at some stage include a gravitationally unstable disc. Initially unstable gas-dust discs may form planets directly…
On the formation of an eccentric disk via disruption of a bulge core near a massive black hole
A. C. Quillen, Alex Hubbard
We consider the possibility that an infalling bulge core or stellar cluster could form an eccentric disk, following tidal disruption by a massive black hole in the center of a gala…
