Abstract
We model the evolution of the selected types of X-ray sources (both with BHs and NSs) for the star formation burst at the Galactic center. For the currently assumed starburst age of 4-7 millions years, our results are consistent with the recent GRANAT X-ray observations of the Galactic center and predict a substantial number of X-ray binaries with black holes. In addition we made a very simple model of the spatial distribution of the X-ray sources, which is also consistent with the GRANAT observations. The results can be applied to other starformation regions.
