The Chemical Composition of the Sun
The solar chemical composition is an important ingredient in our understanding of the formation, structure, and evolution of both the Sun and our Solar System. Furthermore, it i...

We reexamine closely the solar photospheric line at 6300 A, which is\nattributed to a forbidden line of neutral oxygen, and is widely used in\nanalyses of other late-type stars....
New Light on Stellar Abundance Analyses: Departures from LTE and Homogeneity
▪ Abstract The information on the chemical compositions of stars encoded in their spectra plays a central role in contemporary astrophysics. Stellar element abundances are, howe...
A Reappraisal of the Solar Photospheric C/O Ratio
An accurate determination of photospheric solar abundances requires detailed modeling of the solar granulation and accounting for departures from local thermodynamical equilibri...
Line formation in solar granulation
The possibility of unaccounted for opacity sources in the UV for late-type stars has often been invoked to explain discrepancies between predicted and observed flux distribution...
Line formation in solar granulation
The solar photospheric oxygen abundance has been determined from [O I], O I, OH vibration-rotation and OH pure rotation lines by means of a realistic time-dependent, 3D, hydrody...
Line formation in solar granulation
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, ...
Inelastic H+Li and H<sup>-</sup>+Li<sup>+</sup>collisions and non-LTE Li I line formation in stellar atmospheres
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 HD 140283 and HD 84937
\n The lithium abundances in metal-poor halo stars are of \nimportance for cosmology, galaxy evolution and stellar structure. \nIn an attempt to study possible systematic errors...
