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.

The Galactic Bulge

2014
I will give a brief overview of galactic bulges and then discuss in more detail what is known about the bulge of our Galaxy. The Milky Way has a small boxy/peanut-shaped bulge which we believe formed via instabilities of the disk rather than through mergers.

The nature of the Galactic bulge

Monthly Notices of the Royal Astronomical Society, 1988
The bulge of the Galaxy as seen by IRAS forms a spatially concentrated system of long period cool variable stars. From the period distribution we show that a significant fraction of the IRAS bulge is younger than the globular cluster system. Thus the metal rich stars in the central ∼1 kpc of the Galaxy are not obviously part of the extended stellar ...

The Galactic bulge and halo

Publications of the Astronomical Society of the Pacific, 1993
The relationship between the Galactic halo and bulge is discussed, with reference to early results from a survey for K giants in a field 2 kpc from the Galactic center and Zinn's (1992) data on globular-cluster kinematics. The data are currently too meager to decide whether the inner halo shades gradually into the bulge, although there are some ...
