Beskrivning

This textbook describes the equipment, observational techniques, and analysis used in the investigation of stellar photospheres. Now in its fourth edition, the text has been thoroughly updated and revised to be more accessible to students. New figures have been added to illustrate key concepts, while diagrams have been redrawn and refreshed throughout. The book starts by developing the tools of analysis, and then demonstrates how they can be applied. Topics covered include radiation transfer, models of stellar photospheres, spectroscopic equipment, how to observe stellar spectra, and techniques for measuring stellar temperatures, radii, surface gravities, chemical composition, velocity fields, and rotation rates. Up-to-date results for real stars are included. Written for starting graduate students or advanced undergraduates, this textbook also includes a wealth of reference material useful to researchers. eBook formats include color imagery while print formats are greyscale only; a wide selection of the color images are available online.

Mer om författaren

David F. Gray is a Professor Emeritus of Astronomy at Western University, London, Ontario, Canada, where he has held positions since 1966. He was president of IAU Commission 36, on the Theory of Stellar Atmospheres 1988–1991, and served on the observing-time allocation panels of the Hubble Space Telescope and the Canada–France–Hawaii telescope. He is a member of the Canadian Astronomical Society, the International Astronomical Union, Sigma Xi Honorary Society, and the American Astronomical Society, and has served on numerous organizing committees for astronomical symposia. He was an invited lecturer at the Canary Islands Winter School of Astrophysics, the Catania Observatory, and the Beijing Observatory.

Recensioner i media

'Gray's newest edition has made several key improvements that will render it an important book not only for stellar atmospheres and evolution courses, but also for courses involving modern instrumentation techniques or for anyone working in the field of exoplanets. Each chapter is clearly and logically laid out and extensively referenced, including exercises to support scaffolded learning throughout the undergraduate and graduate curriculum; this makes the book an easy choice for professors teaching both introductory and upper level courses. Gray's new book is destined to become an essential companion for every professional astronomer whose research is impacted by observational effects and the inner workings of stellar photospheres.' Prof. Michelle J. Creech-Eakman, New Mexico Tech
