Instability and breaking of internal waves in a horizontal shear layer
Samuel F. Lewin, Alexis K. Kaminski, Arun Balakrishna +1
The behaviour of internal waves propagating in a background shear flow is studied in the case where the direction of shear is orthogonal to gravity. Ray-tracing theory is used to p…

Nonmodal growth and optimal perturbations in magnetohydrodynamic shear flows
Adrian E. Fraser, Alexis K. Kaminski, Jeffrey S. Oishi
In astrophysical shear flows, the Kelvin-Helmholtz (KH) instability is generally suppressed by magnetic tension provided a sufficiently strong streamwise magnetic field. This is of…
