Scientific paper

Data on seven spectrum binaries having a massive invisible component are analyzed with the aim of detecting the presence of relativistic components (the presence of relativistic stars in binary systems was previously suggested). The contributions of invisible components to the spectra of these stars are studied. It is shown that the weakness of massive invisible components as compared to visible components is the reason for their invisibility. The analysis indicates that HD 31109 (61 omega-Eri) is best suited for the search for a black hole.-
