X-ray sources
Abstract
The lectures cover galactic X-ray sources and the observational situation of black holes. Observational techniques used in X-ray astronomy, in particular the Uhuru satellite, are explained. An outline is given of the X-ray sky currently observed, including the rough distribution and general characteristics of the individual sources, specifically the binary sources. A detailed treatment is devoted to the binary X-ray pulsars, Centaurus X-3 and Hercules X-1. The evidence for black holes is discussed. A review is made of the observational data on Cygnus X-1 which led to the conclusion that it is a black hole. The possibilities for other sources are discussed. Recent work on other binary sources and on the class as a whole is considered. A canonical standard model for the binary X-ray sources is presented.
