... We address a question if globular clusters (GC) in a protogalaxy could for some time evolve chemically as isolated systems, enriching themselves with heavy elements produced in first supernova events that follow initial star formation. We determine both the critical mass of a protoglobular cluster that is needed to retain the ejecta of the very first supernova, and the critical energy (i.e., number of supernovae) that is needed to expel the residual gas from a cluster of a given mass. ...

The black hole. ... The black holes are generated in the result of a collapse of giant stars with the mass more than three Sun's masses. ... And moreover the gas near the neutron star or the black hole will get hot and will become a source of high energetic electromagnetic radiation in X-rays and gamma range. ... In the majority of double systems, being the sources of X-rays radiation, the invisible component mass does not exceed the two solar masses, so it is a neutron star. ...
