The Kelvin-Helmholtz instability in astrospheres.

Videos are isolines of the Mach number in the entire flow area versus time. You can observe the evolution of the Kelvin-Helmholtz instability. Video_1 shows the flow with the parameter \(\chi = 1.6\) and \(M_\infty = 3\). It's almost a steady stream. Video_2 shows the flow with the parameter \(\chi = 17\) and \(M_\infty = 3\). There is a very strong instability.
