PERHAPS A GIFT VOUCHER FOR MUM?: MOTHER'S DAY
Richard Walker spent his career in civil engineering, planning large projects such as power plants, dams and tunnels. Now retired, in the last ten years he has focused increasingly on stellar astronomy and on the indispensable key to this topic - spectroscopy. He undertook a large observing project to record and document the spectra of the most important astronomical objects, and chose to share this gathered information for the benefit of other amateurs worldwide.
'Spectroscopy is to astronomy what fingerprints are to forensic investigators. Walker has put together one of the most comprehensive references on the subject published to date ... he has compiled an atlas of spectra from a variety of astronomical sources that can be used to classify almost any object observable with telescopes that are typically available to amateurs. This book nicely bridges the vast gap between what students will find in most textbooks and the references used by practitioners. Want to tell a white dwarf star from a red giant star? A nebula from a galaxy? Here's how! This richly illustrated atlas of spectra makes the identification process relatively easy. Moreover, the introduction to each chapter provides an accessible primer on the astrophysics behind the spectra. An extensive bibliography will lead the novice spectroscopist into as much detail as desired ... This labor of love belongs on any serious amateur's desk - even professionals will find it quite useful.' T. D. Oswalt, Choice 'Trypsteen and Walker's Spectroscopy for Amateur Astronomers does a thorough job of explaining the science of spectroscopy and should help interested amateurs with equipment choices and processing; the Spectral Atlas for Amateur Astronomers gives them everything else they'll need, namely, a variety of documents and sample spectra for popular targets. It brings together the spectra for the main stellar classes, as well as spectra from stars at various stages of development (from protostars all the way through the stellar life cycle to their transformation into planetary nebulae, supernovae, or white dwarfs). The atlas also includes documents and spectra for star clusters, extragalactic objects, and emission nebulae. Pair this book with Marc F. M. Trypsteen and Richard Walker's Spectroscopy for Amateur Astronomers and you'll have a comprehensive package on spectroscopy.' S. N. Johnson-Roehr, Sky & Telescope: The Essential Guide to Astronomy '... a very good atlas that students, from undergraduate to Ph.D., and instructors will find handy for a quick reference.' B. Ishak, Contemporary Physics
