Granulation signatures in 3D hydrodynamical simulations: evaluating background model performance using a Bayesian nested sampling framework
Jens R. Larsen, Mia S. Lundkvist, Guy R. Davies +5
Understanding the granulation background signal is of vital importance when interpreting the asteroseismic diagnostics of solar-like oscillators. Various descriptions exist in the…
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…
On the computation of eigenfrequencies for equilibrium models including turbulent pressure
T. Sonoi, K. Belkacem, M. -A. Dupret +4
The space-borne missions have provided a wealth of highly accurate data. However, our inability to properly model the upper-most region of solar-like stars prevents us from making…
Stellar granulation as seen in disk-integrated intensity. II. Theoretical scaling relations compared with observations
R. Samadi, K. Belkacem, H. -G. Ludwig +9
A large set of stars observed by CoRoT and Kepler shows clear evidence for the presence of a stellar background, which is interpreted to arise from surface convection, i.e., granul…
3D hydrodynamical CO5BOLD model atmospheres of red giant stars: I. Atmospheric structure of a giant located near the RGB tip
H. -G. Ludwig, A. Kucinskas
We investigate the character and role of convection in the atmosphere of a prototypical red giant located close to the red giant branch (RGB) tip with atmospheric parameters, Teff=…
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…
