Three-dimensional hydrodynamical CO5BOLD model atmospheres of red giant stars VI. First chromosphere model of a late-type giant
Sven Wedemeyer, Arunas Kucinskas, Jonas Klevas +1
Although observational data unequivocally point out to the presence of chromospheres in red giant stars, no attempts have been made so far to model them using 3D hydrodynamical mod…
Synthetic activity indicators for M-type dwarf stars
Sven Wedemeyer, Hans-Günter Ludwig
Here, we present a set of time-dependent 3D RMHD simulations of a M-dwarf star representative of AD Leo, which extend from the upper convection zone into the chromosphere. The 3D m…
Three-dimensional magnetohydrodynamic simulations of M-dwarf chromospheres
S. Wedemeyer, H. -G. Ludwig, O. Steiner
We present first results from three-dimensional radiation magnetohydrodynamic simulations of M-type dwarf stars with CO5BOLD. The local models include the top of the convection zon…
Numerical simulation of the three-dimensional structure and dynamics of the non-magnetic solar chromosphere
Sven Wedemeyer, Bernd Freytag, Matthias Steffen +2
Three-dimensional numerical simulations with CO5BOLD, a new radiation hydrodynamics code, result in a dynamic, thermally bifurcated model of the non-magnetic chromosphere of the qu…
