Chemical Evolution in the Carina Dwarf Spheroidal
A. Koch, E. K. Grebel, D. Harbeck +5
We present metallicities for 487 red giants in the Carina dwarf spheroidal (dSph) galaxy that were obtained from FLAMES low-resolution Ca triplet (CaT) spectroscopy. We find a mean…
R-process and alpha-elements in the Galactic disk: Kinematic correlations
Andreas Koch, E. K. Grebel
Recent studies of elemental abundances in the Galactic halo and in the Galactic disk have underscored the possibility to kinematically separate different Galactic subcomponents. Co…
Spectroscopy of PNe in Sextans A, Sextans B, NGC 3109 and Fornax
Alexei Y. Kniazev, Eva K. Grebel, Alexander G. Pramskij +1
Planetary nebulae (PNe) and HII regions provide a probe of the chemical enrichment and star formation history of a galaxy from intermediate ages to the present day. We present the…
The Evolutionary History of Local Group Irregular Galaxies
Eva K. Grebel
Irregular (Irr) galaxies are gas-rich objects with recent or ongoing star formation. In absence of spiral density waves, star formation occurs largely stochastically. The scattered…
