The Unsteady Taylor--Vortex Dynamo is Fast
Liam O'Connor, Daniel Lecoanet, Geoffrey M. Vasil +6
Astrophysical and geophysical fluids commonly generate organized magnetic fields, despite having enormous magnetic Reynolds numbers and abundant small-scale turbulence. F…
Meridional circulation molecular-weighted
Deepayan Banik, Kristen Menou, Evan H. Anders
Meridional circulation in stratified stellar/planetary interiors in the presence of stable molecular weight gradients remains poorly understood, thereby affecting angular momentum…
Morphological Regimes of Rotating Moist Convection
Whitney T. Powers, Adrian E. Fraser, Evan H. Anders +2
Moist convection is a physical process where the latent heat released by condensation acts as a buoyancy source that can enhance or even trigger an overturning convective instabili…
Multiple scales analysis of a nonlinear timestepping instability in simulations of solitons
Benjamin A. Hyatt, Daniel Lecoanet, Evan H. Anders +1
The susceptibility of timestepping algorithms to numerical instabilities is an important consideration when simulating partial differential equations (PDEs). Here we identify and a…
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…
