This book is a quantitative introduction to what is known or theorized about the structure and evolution of galactic systems. It begins with a general introduction to galaxies and a summary of our empirical observations of galaxies in the universe, including our own. There are then three chapters on galactic structure: the manner in which motions of stars determine galactic shape, the determination of galactic masses, and the structure of discs in spirals. Galactic evolution, especially changes in chemical composition over time, is then covered. The book concludes with a discussion of the origin of galaxies and their relation to more general questions in cosmology. The presentation is sufficiently mathematical so that quantitative results can be discussed in detail. Throughout, the author stresses what are currently accepted results and what theories may need revision in what continues to be a rapidly developing subject.
"...a valuable summary for both specialist and nonspecialist readers." P.J.E. Peebles, Choice
Galaxies are large systems of stars, some of which contain interstellar gas and dust. They also contain much invisible matter, which may be in the form of weakly interacting elementary particles. This introductory textbook describes the properties of galaxies and how to interpret galactic systems.
This new textbook on the properties of galaxies is suitable for undergraduates who require a complete account with some mathematical presentation. Neither elementary nor advanced, but simply introductory!
'Galaxies are the principal component of the Universe. This is an introductory textbook on the observed properties of galaxies, and the way in which these can be interpreted. Professor Tayler covers the motions of stars within galaxies, galactic structure, galactic evolution, and cosmology. In this complete treatment there is sufficient mathematics to enable the discussion to be at the right level for undergraduates, but it is not as formidable as an advanced treatise.\n
A quantitative introduction to what is known or theorized about the structure and evolution of galaxies--large systems of stars containing interstellar gas, dust and invisible matter--is sufficiently mathematical so that quantitative results can be discussed in detail.
Includes bibliographical references (p. 204-205) and index.
