Binary Stars • Double acts • The Dog Star's little 'Pup' • X-rated binaries • Binary stars come in all kinds of combinations, from strongly interacting contact binaries to ‘hang loose’ doubles. We take a close look at four real life examples of multiple star systems: omicron Eridani, epsilon Lyrae, Castor, and Mizar and Alcor. Neil English revisits one of the most famous double stars in the night sky – Sirius and it’s little pup: a white dwarf companion. When things get really heated between binary stars, they can produce a whole range of high-energy phenomena visible at X-ray wavelengths and beyond. Welcome to the world of plasma outflows, X-ray binaries and colliding wind binaries.
