Astro-Spectroscopy: the secret life of the stars ~ Sebastian von Harrach & Roger Wood

Spectroscopic observations of celestial objects have revealed a wealth of detail about their compositions, motions and evolution. In a lightning tour through a vast subject Sebastian and Roger aim to touch on how and why spectra are formed; give some history of spectroscopy in astronomy; indicate the instruments used at the telescope; and outline some of the science to be gleaned from astronomical spectra.
