HYDROMAGNETIC SURFACE WAVES IN A CONDUCTING LIQUID SURROUNDED BY A COMPRESSIBLE GAS,
Abstract
A study was made of those surface waves that can propagate along a plane interface separating a conducting (incompressible) liquid from a non-conducting, compressible gas, when there is a static magnetic field parallel to the interface. For any given direction of propagation (except exactly perpendicular to the magnetic lines), a critical field strength was found above which surface Alfven waves cannot exist. Instead, at these strong magnetic fields, there are surface sound waves in the gas. The critical magnetic field at which the transition from Alfven-type to sound-type surface waves takes place is practically independent of the gas density, depending essentially only on its temperature.
