We focus on the planar fast and slow magnetosound waves in the geometry of a flow where the wave vector forms an arbitrary angle θ with the equilibrium straight magnetic field. Nonlinear distortions of a modulated signal in the magnetic gas are considered and compared to that in unmagnetised gas. The case of acoustical activity of a plasma is included into consideration. The resonant three-wave non-collinear interactions are also discussed. The results depend on the degree of non-adiabaticity of a flow, θ, and plasma-β.}, type={Article}, title={Non-Linear Interaction of Harmonic Waves in a Quasi-Isentropic Flow of Magnetic Gas}, URL={http://ochroma.man.poznan.pl/Content/117158/PDF/aoa.2020.134064.pdf}, doi={10.24425/aoa.2020.134064}, keywords={non-linear magnetoacoustics, adiabatical instability, acoustic activity, three-wave interaction}, }
