Compact X-ray sources.
Abstract
A compact X-ray source is a source which is identified with a stellar object, or exhibits variability in its X-ray intensity by a factor 2 on a time scale of days or less. The observed properties of compact X-ray sources are examined. A large fraction of the sources studied are members of binary systems. Questions concerning close binary models are explored, giving attention to aspects of mass exchange and the formation of a disk, white dwarfs, neutron stars, and the evolution of close binaries into X-ray stars. Problems regarding the interpretation of the observations are considered, taking into account pulsating X-ray sources, Cyg X-1, Sco X-1, and Cyg X-2.
