Testing the 3-equation Kuhfuss Convection Model using the Sun
T. A. M. Braun, F. Ahlborn, F. Kupka +1
Simplified, one-dimensional models are necessary to model convection in the context of stellar evolution. By including the non-local effects of convection, turbulent convection mod…
Third order correlations and skewness in convection. I. A new approach suitable for three-equation non-local models
F. Kupka
Non-local models of stellar convection can account for mixing effects in regions adjacent to convectively unstable layers and for changes to the mean temperature structure caused b…
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…
3D stellar atmospheres for stellar structure models and asteroseismology
F. Kupka
Convection is the most important physical process that determines the structure of the envelopes of cool stars. It influences the surface radiation flux and the shape of observed s…
Convection in the atmospheres and envelopes of Pre-Main Sequence stars
J. Montalban, F. D'Antona, F. Kupka +1
The Teff location of Pre-Main Sequence (PMS) evolutionary tracks depends on the treatment of over-adiabaticity. Since the convection penetrates into the stellar atmosphere, also th…
A-star envelopes: a test of local and non-local models of convection
F. Kupka, M. H. Montgomery
We present results of a fully non-local, compressible model of convection for A-star envelopes. This model quite naturally reproduces a variety of results from observations and num…
