The Effect of Flow and Magnetic Twist on Resonant Absorption of Slow MHD Waves in Magnetic Flux Tubes
نویسندگان
چکیده
Observations show that there are twisted magnetic flux tubes and plasma flow throughout the solar atmosphere. The main purpose of this work is to obtain damping rate sausage modes in presence twist flow. We dispersion relation for slow continuity an inhomogeneous layer under conditions pores, then we solve it numerically. For selected density profile, field, as a function radius across layer, effect field on resonance absorption at low speed greater than one high speed.

Dynamics of nonlinear resonant slow MHD waves in twisted flux tubes
Nonlinear resonant magnetohydrodynamic (MHD) waves are studied in weakly dissipative isotropic plasmas in cylindrical geometry. This geometry is suitable and is needed when one intends to study resonant MHD waves in magnetic flux tubes (e.g. for sunspots, coronal loops, solar plumes, solar wind, the magnetosphere, etc.) The resonant behaviour of slow MHD waves is confined in a narrow dissipativ...
متن کاملOn the nature of kink MHD waves in magnetic flux tubes
Context. Magnetohydrodynamic (MHD) waves are often reported in the solar atmosphere and usually classified as slow, fast, or Alfvén. The possibility that these waves have mixed properties is often ignored. Aims. The goal of this work is to study and determine the nature of MHD kink waves. Methods. This is done by calculating the frequency, the damping rate and the eigenfunctions of MHD kink wav...

Context. The stability properties of toroidal magnetic flux tubes are relevant for the storage and emergence of magnetic fields in the convective envelope of cool stars. In addition to buoyancyand magnetic tension-driven instabilities, flux tubes are also susceptible to an instability induced by the hydrodynamic drag force. Aims. Following our investigation of the basic instability mechanism in...
