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…
Spectral line asymmetries in the metal-poor red giant HD 122563: CO5BOLD predictions versus observations
J. Klevas, A. Kucinskas, H. -G. Ludwig +3
We study the influence of convection on the asymmetries and Doppler shifts of Fe I spectral lines in the metal-poor red giant HD 122563. To this end, we compute theoretical Fe I li…
Chemical abundances in metal-poor giants: limitations imposed by the use of classical 1D stellar atmosphere models
V. Dobrovolskas, A. Kučinskas, H. -G. Ludwig +3
In this work we have used 3D hydrodynamical (CO5BOLD) and 1D hydrostatic (LHD) stellar atmosphere models to study the importance of convection and horizontal temperature inhomogene…
