摘要: In this paper we study the oscillations of a magnetic medium periodic in the x-direction with B parallel to z in the presence of a steady equilibrium field aligned flow. The case with no gravity and stepwise profile for B (x), allowing a normal mode analysis, is studied and the dispersion relation for linear compressional waves is derived. The propagation of waves is studied in particular case modelling the propagation of waves in the penumbral filamentary structures in the photosphere.
