Nonlinear astrophysical dynamo: Three-mode interaction

  • Satoshi Hinata


The effect of mode-coupling on the temporal variation of the linearly unstable magnetic mode is investigated for weakly unstable dynamos. It is shown that the nonlinear coupling of the unstable mode to itself is the dominant effect which stabilizes the mode at a certain amplitude rather than the coupling to other damped modes.
