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 ...

Kinematics of the Galactic Bulge

1992
We present spectroscopic observations of ~200 giant stars in two fields toward the Galactic bulge. The positions of fields 588 and 589 are at l,b = (8,7) and (12,3), respectively, which corresponds to a Galactocentric distance of ~1.6 kpc for the stars in the bulge.

The Evolution of the Galactic Bulge

1992
The central stellar bulge of the Milky Way is a distinct stellar population with age of order 10 Gyr and abundance range from -1.5 to nearly +1.0 dex. A portion of the AGB population in the bulges of the Milky Way, M31, and M32 is too luminous to have evolved from a stellar population as old as the globular clusters.

Chemistry of the Galactic Bulge

2015
The chemical abundances of the Galaxy tell us about the stellar and interstellar medium (ISM) evolution history. By studying the present-day chemistry of various stars (and the ISM), and combining with stellar evolution models and Galactic evolution models (and star number counts), we can build up a picture of how our Galaxy was formed and how it ...
