Mass Models for Disk and Halo Components in Spiral Galaxies ratios for bulge and disk are assumed, a rotation curve is calculated from the light distribution, and possible differences with the observed rotation data are attributed to a dark halo component. Most authors ( - ) have concentrated on ‘maximum disk’ solutions, in which the mass-to-light rat

Systematic Properties of Extragalactic Globular Clusterstellar evolution, to deduce the formation and early evolution of the Galaxy and to determine the total mass of the Galaxy. Galactic globular clusters are generally acknowledged to be the oldest stellar systems in our Galaxy and hence place a strong constraint on estimates of the age of the universe.

The Stellar Population at the Galactic Centerrmation in other galactic nuclei but also as an example of star formation in a bulge environment. The star formation process in the deep gravitational potential well at the center of a galaxy may well differ from that process in the less extreme circumstances found in a disk.
