Review of the hardback: 'No astrophysicist can be expert in all aspects of the Galactic Halo. What is needed, therefore, is a single volume which brings many areas of halo research together. Hot Stars in the Galactic Halo meets the requirement because it contains review and contributed papers, by recognised experts in each field, all of which are clearly written and have extensive citations of the astronomical literature … Hot Stars in the Galactic Halo will undoubtedly serve as an invaluable reference text for many years to come.' The Observatory

The stars that form a halo around our Galaxy are intriguing; they have abundances of elements that suggest they are old. The properties of these 'hot stars' and similar stars in other galaxies challenge the well-established theory of stellar evolution in many ways. Studying the collective properties of these stars provides important input to many areas of astrophysics - including the formation of our Galaxy, stellar evolution and the stellar populations of other galaxies. The study of hot stars in the halo of our Galaxy is undergoing an exciting renaissance owing to important new observations with the Hubble Space Telescope and ASTRO1 and to techniques recently developed for ground-based observations. Advances in computers have also recently led to a far more detailed and complete theoretical understanding of stellar evolution. This volume, first published in 1994, draws together the proceedings of a conference held in Union College, New York, which gathered experts in the field in question.
