Generation of low-frequency pulsations in magnetic waveguides in the solar atmosphere
Abstract
An analytical conclusion is presented of Schroedinger's nonlinear equation describing the nonlinear dynamics of the envelope of the eigenmodes of the magnetic flux tube in the solar atmosphere within the framework of the ideal magnetic layer approximation. The generation of LF pulsations arising as a result of the instability of the packets of captured modes is investigated, and estimates of the period of LF pulsations for photospheric magnetic tubes are made.
