Abundances in the Galactic bulge

Physica Scripta, 2008
The metallicity distribution and abundance ratios of the Galactic bulge are reviewed. Issues raised by recent work of different groups, in particular the high metallicity end, the overabundance of α-elements in the bulge relative to the thick disc and the measurement of giants versus dwarfs, are discussed.

Molecular abundance variations near our galactic center

New Astronomy, 2005
Millimeter-wave observations of CO, HCO+, HNCO, and SiO molecular lines toward Sgr A show that the prominent gas condensations in this region differ significantly in their chemical properties, which may be a result of gradients in the physical conditions as a function of location.

Abundances in the Galactic Bulge

2006
International audience ; A review is presented on abundance determinations in stars of the Galactic bulge, both in the field and in globular clusters. Previous low-resolution spectroscopy results are revised. Recent high resolution and high S/N spectroscopy results based on Keck-Hires, Gemini-Phoenix and VLT-UVES data are presented.

Abundances in the Galactic Disk

Symposium - International Astronomical Union, 2002
The empirical study of the build-up of chemical abundances in the galactic disk is an important route to our understanding of the history of the Galaxy. It supplies a wealth of constraints to the models and simulations being done. There are, however, still many unanswered questions concerning the details of the abundance patterns, and many ...

Stellar nucleosynthesis and galactic abundances

AIP Conference Proceedings, 2001
Galactic abundances are neither constant in time nor do they evolve in a simple fashion, e.g., by an enrichment of heavy elements in constant relative proportions. Instead, their evolution in space and time reflects the history of star formation and the lifetimes of the diverse contributing stellar objects.

Chemical Abundances of Galactic Planetary Nebulae

1992
The chemical composition of 86 planetary nebulae from the Strasbourg-ESO survey are analysed (Acker et al., 1989; Koppen et al., 1991). Strong correlations between O, S, Ar, as well as between N and N/O are found. Galactic radial gradients for the abundances of He, S, and Ar in the old disk nebulae are found in accord with the results of Faundez-Albans
