Variable Stars: Observing Stellar Evolution

Alan Plummer

Variable Stars South, American Association of Variable Star Observers, Linden Observatory

The observation and study of variable stars is uniquely tied to stellar evolution. Over time observers can gain a rare perspective into the lives of stars; not, as is usual, from books alone, but through the telescope. From inconstant newborn stars, to old stars ponderously shaking off their envelopes, and exotic binary systems, the observations of variable star observers are used by astronomers to probe the nature of stars.
This presentation gives some examples of real time stellar evolution, including some really spectacular events, and describes how and why to get involved in this most rewarding field.
