M 31, M 33 and the Milky Way: Similarities and Differences
Published online by Cambridge University Press: 25 September 2002
Abstract
The large galaxies in the Local Group, as all disk galaxies, have diverse stellar populations. A better understanding of these differences, and a physical understanding of the causes, requires more detailed study of the older populations. This presents a significant challenge to GAIA but the scientific returns are also significant.
