The 3D non-LTE solar nitrogen abundance from atomic lines
A. M. Amarsi, N. Grevesse, J. Grumer +3
Nitrogen is an important element in various fields of stellar and Galactic astronomy, and the solar nitrogen abundance is crucial as a yardstick for comparing different objects in…
Line formation in solar granulation VI. [C I], C I, CH and C2 lines and the photospheric C abundance
M. Asplund, N. Grevesse, A. J. Sauval +2
The solar photospheric carbon abundance has been determined from [C I], C I, CH vibration-rotation, CH A-X electronic and C2 Swan electronic lines by means of a time-dependent, 3D,…
The impact of non-LTE effects and granulation inhomogeneities on the derived iron and oxygen abundances in metal-poor halo stars
Nataliya Shchukina, Javier Trujillo Bueno, Martin Asplund
This paper presents the results of a detailed theoretical investigation of the impact of non-LTE effects and of granulation inhomogeneities on the derived iron and oxygen abundance…
Line formation in solar granulation: IV. [O I], OI and OH lines and the photospheric O abundance
M. Asplund, N. Grevesse, A. J. Sauval +2
The solar photospheric oxygen abundance has been determined from [OI], OI, OH vibration-rotation and OH pure rotation lines by means of a realistic time-dependent, 3D, hydrodynamic…
Inelastic H+Li and H^-+Li^+ collisions and non-LTE Li I line formation in stellar atmospheres
P. S. Barklem, A. K. Belyaev, M. Asplund
Rate coefficients for inelastic collisions between Li and H atoms covering all transitions between the asymptotic states Li(2s,2p,3s,3p,3d,4s,4p,4d,4f)+H(1s) and Li^+ +H^- are pres…
Multi-level 3D non-LTE computations of lithium lines in the metal-poor halo stars HD140283 and HD84937
M. Asplund, M. Carlsson, A. Botnen
The lithium abundances in metal-poor halo stars are of importance for cosmology, galaxy evolution and stellar structure. In an attempt to study possible systematic errors in the de…
