Swaying oscillations in Rayleigh-Bénard convection cast new light on solar convection
F. Kupka, D. Fabbian, F. Zaussinger +2
Horizontally-periodic Boussinesq Rayleigh-Bénard Convection (RBC) is a simple model system to study the formation of large-scale structures in turbulent convective flows. We perfor…
Layer formation in double-diffusive convection over resting and moving heated plates
Florian Zaussinger, Friedrich Kupka
We present a numerical study of double-diffusive convection characterized by a stratification unstable to thermal convection while at the same time a mean molecular weight (or solu…
Mixing and Overshooting in Surface Convection Zones of DA White Dwarfs: First Results from ANTARES
F. Kupka, F. Zaussinger, M. H. Montgomery
We present results of a large, high resolution 3D hydrodynamical simulation of the surface layers of a DA white dwarf (WD) with K and using the ANTA…
The effects of rotation on a double-diffusive layer in a rotating spherical shell
Patrick Blies, Friedrich Kupka, Florian Zaussinger +1
So far, numerical studies of double-diffusive layering in turbulent convective flows have neglected the effects of rotation. We undertake a first step into that direction by invest…
Realistic Simulations of Stellar Surface Convection with ANTARES: I. Boundary Conditions and Model Relaxation
H. Grimm-Strele, F. Kupka, B. Löw-Baselli +3
We have implemented open boundary conditions into the ANTARES code to increase the realism of our simulations of stellar surface convection. Even though we greatly benefit from the…
Semiconvection: numerical simulations
F. Zaussinger, H. Spruit
A grid of numerical simulations of double-diffusive convection is presented for the astrophysical case where viscosity (Prandtl number Pr) and solute diffusivity (Lewis number Le)…
Semiconvection
F. Zaussinger, H. C. Spruit
A grid of numerical simulations of double-diffusive convection is presented for astrophysical conditions. As in laboratory and geophysical cases convection takes place in a layered…
Simulations of stellar convection, pulsation and semiconvection
Herbert J. Muthsam, Friedrich Kupka, Eva Mundprecht +3
We report on modelling in stellar astrophysics with the ANTARES code. First, we describe properties of turbulence in solar granulation as seen in high-resolution calculations. Then…
