Horizontal shear instabilities at low Prandtl number
P. Garaud
Turbulent mixing in the radiative regions of stars is usually either ignored or crudely accounted for in most stellar evolution models. However, there is growing theoretical and ob…
The interaction between shear and fingering (thermohaline) convection
P. Garaud, A. Kumar, J. Sridhar
Fingering convection is a turbulent mixing process that can occur in stellar radiative regions whenever the mean molecular weight increases with radius. In some cases, it can have…
The effect of rotation on fingering convection in stellar interiors
S. Sengupta, P. Garaud
We study the effects of rotation on the growth and saturation of the double-diffusive fingering (thermohaline) instability at low Prandtl number. Using direct numerical simulations…
Layer Formation in Sedimentary Fingering Convection
J. F. Reali, P. Garaud, A. Alsinan +1
When particles settle through a stable temperature or salinity gradient they can drive an instability known as sedimentary fingering convection. This phenomenon is thought to occur…
Double-diffusive mixing in stellar interiors in the presence of horizontal gradients
Michael Medrano, Pascale Garaud, Stephan Stellmach
We have identified an important source of mixing in stellar radiation zones, that would arise whenever two conditions are satisfied: (1) the presence of an inverse vertical composi…
Numerically determined transport laws for fingering ("thermohaline") convection in astrophysics
Adrienne Traxler, Pascale Garaud, Stephan Stellmach
We present the first three-dimensional simulations of fingering convection performed in a parameter regime close to the one relevant for astrophysics, and reveal the existence of s…
