... The numbers of three types of compact binaries containing accreting NSs and BHs, which are most interesting from the point of view of their observational appearances, have been calculated as a function of time: i) X-ray transient source containing a NS in an eccentric orbit around a main sequence Be-star (the observed prototype: A0535+26), ii) BH The evolution of the selected types of X-ray binaries during the first 10 million years after the starburst onset is presented in Fig. ...

... The ELG candidates were selected from the digitized objective prism plates of the Hamburg Quasar Survey. ... The low-resolution spectra, which have 10-20 spectral points per object, already allow the detection of strong emission lines, in particular for ELGs with prominent [O III ] 4959,5007 ? ... The selection is biased for the [O III ] lines compared to the [O II ] line because of linear dispersion, favoring the detection of narrow lines near the red end of the objective prism spectra. ...
