Atomic diffusion and mixing in old stars II. Observations of stars in the globular cluster NGC 6397 with VLT/FLAMES-GIRAFFE
K. Lind, A. J. Korn, P. S. Barklem +1
Evolutionary trends in the surface abundances of heavier elements have recently been identified in the globular cluster NGC 6397 ([Fe/H]=-2), indicating the operation of atomic dif…

The sensitivity of Lick indices to abundance variations
A. J. Korn, C. Maraston, D. Thomas
We present results of model atmosphere/line formation calculations which quantitatively test how the 21 classical and four higher-order Balmer-line Lick/IDS indices (Worthey et al.…

Kinetic equilibrium of iron in the atmospheres of cool stars III. The ionization equilibrium of selected reference stars
A. J. Korn, J. Shi, T. Gehren
Non-LTE line formation calculations of Fe I are performed for a small number of reference stars to investigate and quantify the efficiency of neutral hydrogen collisions. Using the…
