Claims

C1strongest claim

The instability is identified as resonant, peaking when the wave phase velocity matches the mean flow velocity, with the growth rate decreasing for higher-order modes... the instability vanishes in the vortex sheet limit, distinguishing it from the classical Kelvin-Helmholtz mechanism. These findings suggest that this specific instability holds significant potential for explaining the problem of observed boundaries between isotropic and anisotropic proton temperature regions in a low-beta solar wind plasma.

C2weakest assumption

The reduction of the governing wave equation to an exactly solvable form assumes a smooth hyperbolic velocity profile together with spatially homogeneous density and magnetic field in the unperturbed state; the 16-moment closure must remain valid throughout the linear growth phase.

C3one line summary

An exact analytical modal analysis yields a resonant shear-flow instability in supersonic anisotropic plasmas that vanishes in the vortex-sheet limit and is distinct from Kelvin-Helmholtz.
