Granulation in K-type dwarf stars. II. Hydrodynamic simulations and 3D spectrum synthesis
Aims: To explore the impact of surface inhomogeneities on stellar spectra, granulation models need to be computed. Ideally, the most fundamental characteristics of these models should be carefully tested before applying them to the study of more practical matters, such as the derivation of photospheric abundances. Our goal is to analyze the
