Reality of Moving Groups in the Galaxy
G. M. De Silva, K. C. Freeman, J. Bland-Hawthorn +1
The existence of old dispersed stellar groups within the Milky Way disk is still controversial. Are they the debris of ancient star-forming aggregates, or short-lived artifacts of…
Nucleosynthetic signatures of the first stars
Anna Frebel, Wako Aoki, Norbert Christlieb +16
The chemically most primitive stars provide constraints on the nature of the first stellar objects that formed in the Universe; elements other than hydrogen, helium and traces of l…
Uncertainties in stellar abundance analyses
Martin Asplund
Over the last half-century quantitative stellar spectroscopy has made great progress. However, most stellar abundance analyses today still employ rather simplified models, which ca…
Globular cluster abundances in the light of 3D hydrodynamical model atmospheres
Martin Asplund
The new generation of 3D hydrodynamical model atmospheres have been employed to study the impact of a realistic treatment of stellar convection on element abundance determinations…
New generations of stellar model atmospheres
Martin Asplund
Stellar model atmospheres form the basis for any element abundance determination and hence are crucial ingredients for studies of stellar, galactic and cosmic evolution. With recen…
Radiative transfer in 3D model stellar atmospheres
Martin Asplund, Remo Collet
Recently 3D hydrodynamical simulations of stellar surface convection have become feasible thanks to advances in computer technology and efficient numerical algorithms. Available ob…
