Review: progress in NLTE calculations and their application to large data-sets
L. Mashonkina
One of the major tasks in interpretation of data from large-scale stellar surveys is to determine the fundamental atmospheric parameters such as effective temperature, surface grav…
Atomic diffusion and mixing in old stars IV: Weak abundance trends in the globular cluster NGC 6752
Pieter Gruyters, Andreas J. Korn, Olivier Richard +5
Atomic diffusion in stars can create systematic trends of surface abundances with evolutionary stage. Globular clusters offer useful laboratories to put observational constraints o…
Signs of atmospheric inhomogeneities in cool stars from 1D-NLTE analysis of iron lines
L. Mashonkina, H. -G. Ludwig, A. Korn +2
For the well studied halo star HD 122563 and the four stars in the globular cluster NGC 6397, we determine NLTE abundances of iron using classical plane-parallel model atmospheres.…
Influence of Departures from LTE on Oxygen Abundance Determination
T. M. Sitnova, L. I. Mashonkina, T. A. Ryabchikova
We performed non-LTE calculations for O I with the plane-parallel model atmospheres for a set of stellar parameters corresponding to A-K type stars. The model atom of Przybilla et…
