An extended and refined grid of 3D STAGGER model atmospheres. Processed snapshots for stellar spectroscopy
Luisa F. Rodríguez Díaz, Cis Lagae, Anish M. Amarsi +6
Context: Traditional one-dimensional (1D) hydrostatic model atmospheres introduce systematic modelling errors into spectroscopic analyses of FGK-type stars. Aims: We present an upd…
Non-LTE line formation of Fe in late-type stars IV: Modelling of the solar centre-to-limb variation in 3D
K. Lind, A. M. Amarsi, M. Asplund +7
Our ability to model the shapes and strengths of iron lines in the solar spectrum is a critical test of the accuracy of the solar iron abundance, which sets the absolute zero-point…
Chemical abundances in the multiple sub-giant branch of 47 Tucanae: insights on its faint sub-giant branch component
A. F. Marino, A. P. Milone, L. Casagrande +8
The globular cluster 47 Tuc exhibits a complex sub-giant branch (SGB) with a faint-SGB comprising only about the 10% of the cluster mass and a bright-SGB hosting at least two disti…
Fundamental properties of the Population II fiducial stars HD 122563 and Gmb 1830 from CHARA interferometric observations
O. L. Creevey, F. Thévenin, T. S. Boyajian +17
We have determined the angular diameters of two metal-poor stars, HD 122563 and Gmb 1830, using CHARA and Palomar Testbed Interferometer observations. For the giant star HD 122563,…
