New Abundances for Old Stars - Atomic Diffusion at Work in NGC 6397
A. J. Korn, F. Grundahl, O. Richard +5
A homogeneous spectroscopic analysis of unevolved and evolved stars in the metal-poor globular cluster NGC 6397 with FLAMES-UVES reveals systematic trends of stellar surface abunda…
A non-LTE study of neutral and singly-ionized calcium in late-type stars
L. Mashonkina, A. J. Korn, N. Przybilla
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 varies from…
A probable stellar solution to the cosmological lithium discrepancy
A. J. Korn, F. Grundahl, O. Richard +5
The measurement of the cosmic microwave background has strongly constrained the cosmological parameters of the Universe. When the measured density of baryons (ordinary matter) is c…
Barium even-to-odd isotope abundance ratios in thick disk and thin disk stars
L. Mashonkina, G. Zhao
We present the Ba even-to-odd isotope abundance ratios in 25 cool dwarf stars with the metallicity [Fe/H] ranged between 0.25 and --1.35. Our method takes advantage of the hyperfin…
