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…

3D Simulations Demonstrate Propagating Thermohaline Convection for Polluted White Dwarfs
Imogen G. Cresswell, Adrian E. Fraser, Evan B. Bauer +2
Polluted white dwarfs (WDs) with small surface convection zones deposit significant concentrations of heavy elements to the underlying radiative interior, presumably driving thermo…

Evolution of Semi-convective Staircases in Rotating Flows: Consequences for Fuzzy Cores in Giant Planets
J. R. Fuentes, Bradley W. Hindman, Adrian E. Fraser +1
Recent observational constraints on the internal structure of Jupiter and Saturn suggest that these planets have ``fuzzy" cores, i.e., gradients of the concentration of heavy eleme…
