Nonlinear stability of the dayside cometary ionopause

摘要: The MHD stability of the cometary ionopause is investigated by nonlinear analysis, describing that in terms finite perturbation amplitude both Kelvin-Helmholtz and Rayleigh-Taylor modes. evolution unstable modes examined, determining conditions under which effects are expected to stabilize a growing wave disturbance. analysis applied at Comet Halley Giacobini-Zinner, showing theoretical prediction concerning this interface based on an earlier linear remains valid cases despite stabilization effects. 18 references.
