• Back Reaction to the Spectrum of Magnetic Field in the Kinetic Dynamo Theory. Modified Kulsrud-Anderson Equation.

抄録

We take account of the lowest order back reaction on a fluid and modify the Kulsrud-Anderson equation, ∂ _t {\cal E}_M = 2 γ {\cal E}_M, obtained in the kinetic dynamo theory, where {\cal E}_M is the energy density of the magnetic field. We apply our results to certain astrophysical stages where the magnetic field is expected to be amplified by the dynamo mechanism.
