Effects of Scattering on the Temperature Stratification in 3D Model Atmospheres of Late-Type Stars
Three-dimensional (3D) radiative hydrodynamic model atmospheres of metal-poor late-type stars predict cooler upper photospheric stratifications than their one-dimensional (1D) counterparts. This property of 3D model atmospheres affects the determination of elemental abundances from temperature-sensitive spectral features, with important consequences for galactic chemical evolution studies. In this contribution, we investigate the impact of different approximations of scattering in the...[Show more]
