You can almost touch the stars – An Introduction to Astronomical Spectr oscopy

Even if you wanted to touch a star, they’re all impossibly di stant. In spite of these great distances, astronomers have learned an enorm ous amount about stars. How? The most common method to study the stars is c alled spectroscopy, which is the science of analysing the colourful rainbow spectrum produced by a prism-like device.

Until recently, spectrosco py was too expensive and too complicated for all but a handful of amateurs. Today, though, new tools make spectroscopy accessible to almost all of us. You no longer need a PhD, dark skies, long exposures, enormous aperture … or a big budget! With your current telescope and FITS camera (or a simple w eb cam or even a DSLR without a telescope) you can now easily study the sta rs yourself. Wouldn’t you like to detect the atmosphere on Neptune or the r ed shift of a quasar right from your own backyard?!

This talk, with l ots of interesting examples, will show you what it’s all about and help you understand how spectroscopy is used in research. Even if you are an armcha ir astronomer, understanding this field will enhance your understanding of the things you read and the night sky.

We’ll do a live Q&A after Tom’s 45-minute presentation.
