Klappentext A review, first published in 1994, of studies of the 'hot stars' that comprise a halo around our Galaxy and similar stars in other galaxies. Zusammenfassung This volume! first published in 1994! draws together the proceedings of a conference held in Union College! New York! which gathered experts on 'hot stars'. The result is an intriguing of study of these stars! that comprise a halo around our Galaxy and similar stars in other galaxies - essential reading for graduate students and researchers.
