Deciphering the Enigma of QZ Car

Ed Budding (with help from Stan Walker, Mark Blackford and Roger Butland)

Carter Observatory

The four main components of QZ Car form a pair of close binaries that share a wide orbit with a period of about 50 years. Observing this system is not really as simple as 'two binaries for the price of one', however, as these massive young stars are involved in complex processes of interaction. The present authors have been trying to piece together a comprehensive picture of the system for some time. A review of the various aspects of this effort brings out, in the one target, many of the more general issues in close binary research.
