The combined effects of vertical and horizontal shear instabilities
Pascale Garaud, Saniya Khan, Justin M. Brown
Shear instabilities can be the source of significant amounts of turbulent mixing in stellar radiative zones. Past attempts at modeling their effects (either theoretically or using…
Magnetized fingering convection in stars
Adrian E. Fraser, Sam A. Reifenstein, Pascale Garaud
Fingering convection (also known as thermohaline convection) is a process that drives the vertical transport of chemical elements in regions of stellar radiative zones where the me…
Magnetized oscillatory double-diffusive convection
Amishi Sanghi, Adrian E Fraser, Edward W Tian +1
We study the properties of oscillatory double-diffusive convection (ODDC) in the presence of a uniform vertical background magnetic field. ODDC takes place in stellar regions that…
Resistive instabilities in sinusoidal shear flows with a streamwise magnetic field
Adrian E. Fraser, Imogen G. Cresswell, Pascale Garaud
We investigate the linear stability of a sinusoidal shear flow with an initially uniform streamwise magnetic field in the framework of incompressible magnetohydrodynamics (MHD) wit…
Modeling coexisting GSF and shear instabilities in rotating stars
Eonho Chang, Pascale Garaud
Zahn's widely-used model for turbulent mixing induced by rotational shear has recently been validated (with some caveats) in non-rotating shear flows. It is not clear, however, whe…
Journey to the center of stars: the realm of low Prandtl number fluid dynamics
Pascale Garaud
The dynamics of fluids deep in stellar interiors is a subject that bears many similarities with geophysical fluid dynamics, with one crucial difference: the Prandtl number. The rat…
