1957 S. Pai in Physical Rev. 105 1424/1 Recently the study of magnetohydrodynamics of a compressible fluid, more properly magneto-gas dynamics, has attracted great attention.
1983 Astrophysics & Space Sci. 93 423 (title) Self-similar flows behind cylindrical shock waves in magnetogasdynamics.
1993 Astron. Rep. 37 630/1 Calculations in the ideal magnetogasdynamics approximation are also actively used for structural analysis of dense atmospheric formations.
