✦ Synopsis

A new type of symmetry for the Rayleigh equation is found. For small Atwood number an analytic solution is obtained for a smoothly varying density profile. The spectra of unstable modes are defined. It is shown that a transition layer with finite width can undergo stratification, and velocity shear between new-formed sublayers forms.

The influence of a vertical magnetic field on the stability of a compressible, inviscid Iluid of variable density is investigated. The solution is characterized by a variational principle. Based on it an approximate solution for the fluid of exponentially varying density, confined between two planes
