Query: Mechanism for flow generation/acceleration in dense degenerate stellar
  atmospheres   The mechanism for flow generation in dense degenerate stellar atmospheres is
suggested when the electron gas is degenerate and ions are assumed to be
classical. It is shown, that there is a catastrophe in such system -- fast
flows are generated due to magneto-fluid coupling near the surface. Distance
over which acceleration appears is determined by the strength of gravity and
degeneracy parameter. Application of this mechanism for White Dwarfs'
atmospheres is examined and appropriate physical parameter range for flow
generation/acceleration is found; possibility of the super-Alfv\'enic flow
generation is shown; the simultaneous possibility of flow acceleration and
magnetic field amplification for specific boundary conditions is explored; in
some cases initial background flow can be accelerated 100 and more times
leading to transient jet formation while the Magnetic field amplification is
less strong.
