Disentangling the Hercules stream
T. Bensby, M. S. Oey, S. Feltzing +1
Using high-resolution spectra of nearby F and G dwarf stars, we have investigated the detailed abundance and age structure of the Hercules stream. We find that the stars in the str…
Hercules stream stars and the metal-rich thick disk
T. Bensby, M. S. Oey, S. Feltzing +1
Using the MIKE spectrograph, mounted on the 6.5 m Magellan/Clay telescope at the Las Campanas observatory in Chile, we have obtained high-resolution spectra for 60 F and G dwarf st…
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 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…
Analysis of the Luminosity-Stellar Mass-Metallicity Relation in cosmological simulations
Maria Emilia De Rossi, Patricia Beatriz Tissera, Cecilia Scannapieco
We study the Luminosity-Metallicity Relation and the Stellar Mass-Metallicity Relation by performing chemo-dynamical simulations in a cosmological scenario. Our results predict a t…
Evolution of the Luminosity-Metallicity-Stellar Mass correlation in a hierarchical scenario
Maria Emilia De Rossi, Patricia Beatriz Tissera, Cecilia Scannapieco
We study the evolution of the Stellar Mass-Metallicity Relation and the Luminosity-Metallicity Relation by performing numerical simulations in a cosmological framework. We find tha…
