Searching for the Oldest Stars: Ancient Relics from the Early Universe

German-born astronomer Frebel, an assistant professor of physics at MIT, makes this crash course in astronomy accessible to stargazers of all knowledge levels. She starts with the basics, including a summary of the historical connections between astronomy and physics, and incrementally adds topics of greater technicality%E2%80%94such as the universe's "chemical evolution," the life cycle of stars, the production of heavy elements, and spectral analysis%E2%80%94up to her own research on metal-poor stars. Woven through the science are personal anecdotes from Frebel, which give the impression of a face-to-face lesson with a favorite professor. The information is not organized for ease of reference, but in a manner that flows steadily as new material accretes, making comprehension easier for those with less background knowledge. The sheer density of information can make for slower and more difficult reading, but anyone with a strong interest in astronomy will appreciate the way Frebel employs diagrams and terminology. This book is not an introductory survey of astronomy, but rather an in-depth discussion written by an expert in the field. Frebel offers a handy learning tool for fledgling astronomers and a fascinating, enjoyable look into her own research. (Nov.)
