... In this Section we examine evolution of the number of binary X-ray sources in an arbitrary galaxy. ... However, the problem with its X-ray radiation spectrum remains unsolved because no objects of this type have been observed so far. ... The total X-ray luminosity from different types of objects is traced separately at any instant. First, we calculated the evolution of the X-ray luminosity   assuming a delta-function (instantaneous) shape for the star formation rate. ...
