Entropy-calibrated stellar modeling: Testing and improving the use of prescriptions for entropy of adiabatic convection
L. Manchon, M. Deal, M. -J. Goupil +7
The modeling of convection is a long standing problem in stellar physics. Up-to-now, all ad hoc models rely on a free parameter alpha (among others) which has no real physical just…
MINCE I. Presentation of the project and of the first year sample
G. Cescutti, P. Bonifacio, E. Caffau +20
In recent years, Galactic archaeology has become a particularly vibrant field of astronomy, with its main focus set on the oldest stars of our Galaxy. In most cases, these stars ha…
Abundance of beryllium in the Sun and stars: The role of non-local thermodynamic equilibrium effects
S. Korotin, A. Kučinskas
Earlier studies have suggested that deviations from the local thermodynamic equilibrium (LTE) play a minor role in the formation of Be II 313 nm resonance lines in solar and stella…
Abundances of Mg and K in the atmospheres of turn-off stars in Galactic globular cluster 47 Tucanae
A. Černiauskas, A. Kučinskas, J. Klevas +6
We determined abundances of Mg and K in the atmospheres of 53 (Mg) and 75 (K) turn-off (TO) stars of the Galactic globular cluster 47 Tuc. The obtained abundances, together with th…
Chemical abundances in metal-poor giants: limitations imposed by the use of classical 1D stellar atmosphere models
V. Dobrovolskas, A. Kučinskas, H. -G. Ludwig +3
In this work we have used 3D hydrodynamical (CO5BOLD) and 1D hydrostatic (LHD) stellar atmosphere models to study the importance of convection and horizontal temperature inhomogene…
