Summary: Very engaging and makes a good reference too
Comment: "Stars and their Spectra" is overall a significantly better read than Kaler's earlier work "Stars", which touched on many topics but didn't dive into any of them satisfyingly enough. This book delivers a thorough yet introductory coverage of the science of stellar spectroscopy. As an added bonus, it's very well-written and is great fun to read cover to cover. Kaler clearly harbors great enthusiasm for this subject, particularly when he discusses extreme stars like supergiants and white dwarfs.
Kaler spends the first eighty pages or so covering the basics of how stars work, spectral theory, and history of the modern scheme of spectral classification (OBAFGKM, easily remembered by the popular mnemonic Oh Be A Fine Girl Kiss Me). The meat of the book comes next: a chapter devoted to each letter of the sequence, starting from the cool M stars and working up to the ultra-hot O stars. Here Kaler goes into significant detail on the defining characteristics of each class and how those characteristics manifest themselves physically. We learn how dwarfs, giants, and supergiants may share a spectral class but are fundamentally different (the giants and supergiants almost always aged into that spectral class from a different one). A wealth of other information on each class is presented. We finish up with stars that don't really appear on the regular H-R diagram, such as white dwarfs and neutron stars. Kaler also gives a nice overview at the end of how stars journey along the H-R diagram, changing spectral classes as they age and their internal fusion engines deplete their fuel.
I see stars of a myriad of different colors through my telescope. A few are stunning and a great many come in attractive pairs or multiples. Yet visually they're all points of light with little meaning. It was fascinating to see how much can be learned from analyzing the detailed characteristics of a star's light by dispersing it in a spectrograph. Due to the advancements in this science and the aggregation of data points on the modern H-R diagram, it is often possible to guage a star's size, age, chemical composition, and distance solely from the qualities of its light.
I sell most books after I read them but this one's a keeper and has a permanent spot on the shelf!

Summary: How to make astrophysics interesting and comprehensible
Comment: If you think that star spectrography is an obscure and boring field of research reserved to people with a Cambridge degree, well, you're wrong, and here's why. "Stars And Their Spectra" is yet another marvelous book by James Kaler one of the leading (and still the most underrated!) divulgator of stellar astronomy. It's the natural follow-up of "Stars", Kaler's book on the birth, evolution and death of (guess what?) stars. It explains how the light coming from objects distants thousands of light-years (or more) does contains a wealth of informations on the nature of those little points of light in the night sky. The classification of spectral data, the nature of emission and absorbtion lines, the whole array of concpet behind the analisys of stellar light, it's all presented in a clear manner, with great examples and the right amount of illustrations. Moreover, Kaler it's a divulgator but a scientist too, and he never insults the intelligence of the reader trying to banalize the subject matter. Based on a series of articles appeared on "Sky And Telescope", "The Stars And Their Spectra" will make turn you instantly in an amateur spectrographer...

Summary: Superbly done
Comment: As an amateur astronomer I simply cannot beleive I have gone so long enjoying astronomy without coming to grips with spectra. While the concepts are generally known this book takes the general reader step by step through probably the most important pillar of modern astronomy, analyses of light.
The book requires no advanced mathematics (if it had I wouldnt have understood it) and sticks to good solid concepts.
While it is accessible to the general reader Kaler pulls no punches even when you wish he had, insisting on parsecs instead of lightyears for example. However the joy of him pulling no punches is you are left with a good grounding with which to move onto other works or even do some spectroscopy yourself as I did.
I would commend other astronomy enthusiasts or lovers of space science to get to grips with how we determine the make up of stars and other objects, this is the book to do it.
