Magnetoacoustic surface gravity waves
The effect of gravity on the surface magnetoacoustic waves may be important when considering applications to solar and laboratory plasmas. The linear magnetoacoustic waves, which may appear in a configuration with an interface between two plasmas or a plasma and an ordinary gas, are studied. Compres...

The effect of gravity on the surface magnetoacoustic waves may be important when considering applications to solar and laboratory plasmas.

Magnetoacoustic surface waves are studied in detail in a configuration consisting of an interface between an isothermal plasma and an ordinary gas.
