M3DIS -- A grid of 3D radiation-hydrodynamics stellar atmosphere models for stellar surveys. II. Carbon-enhanced metal-poor stars
Philipp Eitner, Maria Bergemann, Richard Hoppe +6
Understanding the origin and evolution of carbon-enhanced metal-poor (CEMP) stars is key to tracing the Galaxy's early chemical enrichment. We investigate how realistic 3D radiatio…
M3DIS -- A grid of 3D radiation-hydrodynamics stellar atmosphere models for stellar surveys
Philipp Eitner, Maria Bergemann, Richard Hoppe +3
Large-scale stellar surveys, such as SDSS-V, 4MOST, WEAVE, and PLATO, require accurate atmospheric models and synthetic spectra of stars for accurate analyses of fundamental stella…
The benchmark halo giant HD 122563: CNO abundances revisited with three-dimensional hydrodynamic model stellar atmospheres
Remo Collet, Åke Nordlund, Martin Asplund +2
We present an abundance analysis of the low-metallicity benchmark red giant star HD 122563 based on realistic, state-of-the-art, high-resolution, three-dimensional (3D) model stell…
3D LTE spectral line formation with scattering in red giant stars
W. Hayek, M. Asplund, R. Collet +1
We investigate the effects of coherent isotropic continuum scattering on the formation of spectral lines in local thermodynamic equilibrium (LTE) using 3D hydrodynamical and 1D hyd…
Three-dimensional surface convection simulations of metal-poor stars -- The effect of scattering on the photospheric temperature stratification
R. Collet, W. Hayek, M. Asplund +3
Three-dimensional (3D) radiative hydrodynamic model atmospheres of metal-poor late-type stars are characterized by cooler upper photospheric layers than their 1D counterparts. This…
Abundance Analysis of the Halo Giant HD122563 with Three-Dimensional Model Stellar Atmospheres
R. Collet, A. Nordlund, M. Asplund +2
We present a preliminary local thermodynamic equilibrium (LTE) abundance analysis of the template halo red giant HD122563 based on a realistic, three-dimensional (3D), time-depende…
