Propagation of nonlinear longitudinal-transverse waves along magnetic flux tubes in the solar atmosphere. I : Adiabatic waves

摘要: The nonlinear time-dependent response to purely transverse foot point shaking of a vertical magnetic flux tube in the solar atmosphere was studied. adiabatic calculations show generation longitudinal wave mode which has twice frequency wave. amplitude increases with period and magnitude shaking. Due action centrifugal forces significant lifting gas found. A forced oscillator type resonance occurs depends on length
