The measurement of stellar properties such as chemical compositions, masses and ages,
through stellar spectra, is a fundamental problem in astrophysics. Progress in the …

Aims. Non-local thermodynamical equilibrium (NLTE) line formation for neutral and singly-
ionized calcium is considered through a range of spectral types when the Ca abundance …

Context. We describe the atomic and molecular data that were used for the abundance
analyses of FGK-type stars carried out within the Gaia-ESO Public Spectroscopic Survey in …

We investigate the statistical equilibrium of neutral and singly-ionized strontium in late-type
stellar atmospheres. Particular attention is given to the completeness of the model atom …

Data for the broadening of 24188 Fe II lines by collisions with neutral hydrogen atoms have
been computed using the theory of Anstee & O'Mara as extended to singly ionised species …

Potential energy functions of the MgH molecule are investigated by the MRCI method using
large active space and basis sets. The calculations are performed up to the Mg (3s3d, 1D)+ …

The properties of a number of states of calcium are determined from a large basis
configuration interaction calculation. The main focus is on the polarizabilities of the low lying …

Context. Rigorous implementation of the effects of collisions in modeling the formation of the
polarized solar lines is of utmost importance in order to realistically analyze the available …

The dispersion coefficients for the van der Waals interactions for the low lying states of
magnesium (3 s ² 1S e, 3 s 3 p 3P o, 3 s 3 p ¹P o, 3 s 4 s 3S e, 3 s 4 s 1S e, 3 s 3 d 3D e and …

The broadening and shifting of spectral lines induced by collisions with the five noble gases
in both the intercombination 5 s 2 S 0 1→ 5 s 5 p P 1 3 system and the triplet 5 s 5 p P 0, 1, 2 …
