Amateur astronomers and the new golden age of cataclysmic variable star astronomy

Abstract

The study of cataclysmic variable stars has long been a fruitful area of co-operation between amateur and professional astronomers. In this Presidential Address, I shall take stock of our current understanding of these fascinating binary systems, highlighting where amateurs can still contribute to pushing back the frontiers of knowledge. I shall also consider the sky surveys that are already coming on stream, which will provide near continuous and exquisitely precise photometry of these systems. I show that whilst these surveys might be perceived as a threat to amateur observations, they will actually provide new opportunities, although the amateur community shall need to adapt and focus its efforts. I will identify areas where amateurs equipped for either visual observing or CCD photometry can make scientifically useful observations.
