Stellar Populations and the Star Formation History
An early determination of the stellar populations in M33 was the analysis of the stellar photometry obtained by Mould and Kristian (1986), as described in Chap. 8. Their results indicated that the galaxy contains a population of old stars, similar to thos

Preface
This book summarizes the gathering of knowledge of M33 from the 1920s, when Hubble first determined its true nature, to the twenty-first century, when the Hubble Telescope probed deeply into its many secrets. More than our Milky Way or the Andromeda Galaxy, the smaller spiral M33 is the only really typical spiral galaxy of our Local Group. It is neither a giant nor a dwarf. It has a regular symmetrical spiral structure, not conspicuously distorted by recent tidal encounters or interactions. While not face-on, it is not tilted too much (as is the case of M31) to make it difficult to untangle its structure. And it lies near enough to allow us to study its stars in enough detail to measure stellar and cluster ages and chemical composition
