Book Description
This accessible guide presents the astrophysical concepts behind astronomical spectroscopy, covering both the theory and the practical elements of recording, processing, analysing and interpreting your spectra. It covers astronomical objects, such as stars, planets, nebulae, novae, supernovae, and events such as eclipses and comet passages. Suitable for anyone with only a little background knowledge and access to amateur-level equipment, the guide's many illustrations, sketches and figures will help you understand and practise this scientifically important and growing field of amateur astronomy, up to the level of Pro-Am collaborations. Accessible to non-academics, it benefits many groups from novices and learners in astronomy clubs, to advanced students and teachers of astrophysics. This volume is the perfect companion to the Spectral Atlas for Amateur Astronomers, which provides detailed commented spectral profiles of more than 100 astronomical objects.

Book Description
Featuring detailed commented spectral profiles of more than one hundred astronomical objects, in colour, this spectral guide documents most of the important and spectroscopically observable objects accessible using typical amateur equipment. It allows you to read and interpret the recorded spectra of the main stellar classes, as well as most of the steps from protostars through to the final stages of stellar evolution as planetary nebulae, white dwarfs or the different types of supernovae. It also presents integrated spectra of stellar clusters, galaxies and quasars, and the reference spectra of some terrestrial light sources, for calibration purposes. Whether used as the principal reference for comparing with your recorded spectra or for inspiring independent observing projects, this atlas provides a breathtaking view into our Universe's past. The atlas is accompanied and supplemented by Spectroscopy for Amateur Astronomers, which explains in detail the methods for recording, processing, analysing and interpreting your spectra.

Book Description
The purpose of this book is to discuss certain aspects of the theory of the formation and analysis of the line spectrum of a hot gas. The underlying motivation for most of the studies discussed here lies in a desire to develop a physically sound procedure for interpreting the line spectrum of a stellar atmosphere ; correspondingly, the major emphasis is given to problems encountered in astrophysics.

Book Description
The study of stars and their spectra is central to an understanding of classical and modern astronomy. The principal tool for investigating the nature of stars is to observe and interpret their spectra. In this lucid book, James Kaler clearly explains the alphabet of stellar astronomy - from the cool M stars to hot O stars - and tells the story of the evolution of stars and their place in the Universe. Before embarking on a fascinating voyage of cosmic discovery, we are introduced to the fundamental properties of stars, and how they can be categorised. Next, the structure of atoms and the formation of spectra is discussed, as a prelude to a full description of the spectral classification itself. The heart of the book examines each star type in turn and explores their spectra in detail. Notable discoveries and features related to each class sustain the story. There is also a review of unusual stars that cannot easily be classified. Finally, the book closes with a skilful integration of all the data - tracing the paths of birth, life and death of stars on the Hertzsprung-Russell diagram. This book is based on a widely acclaimed series of articles on stellar astronomy which appeared in the magazine Sky and Telescope. It provides an invaluable introduction for observers and students.

Book Description
Despite more than one century of observational stellar spectroscopy, the resulting data are not available in an easily accessible format. The necessity of such basic information is greater than ever, because new wavelength regions (ultraviolet, infrared) are now accessible and because modern receivers can only analyze short stretches of spectra, so that a careful pre-selection of strategic elements is mandatory. This book presents a summary of our knowledge of the behavior of all chemical elements identified in stars, based on observations rather than on their interpretations. Whenever possible the behavior is described quantitatively, with the help of equivalent widths in different types of stars, or different ionization stages, for both absorption and emission features. It will be essential to the spectroscopist when confronted with questions like the following: . What is the behavior of europium in metallic line stars or in S-type stars? Are the neutral lines of this element visible, are they strengthened or weakened with regard to normal dwarfs? A huge amount of data has been gathered by experts in the field and presented in a way that will be invaluable to professional astrophysicists, cosmochemists and their students.
