Chemical anomalies observed in some binary stars are analyzed. These anomalies are caused by: (1) nuclear processes in their cores; (2) diffusive and convective mixing of material between neighboring layers with nuclear heating; and, (3) ejection of matter from the surface into interstellar space. The effect of merging of the components of multiple stars in dense star-dust complexes on the evolution of the chemical composition is examined. It is shown that the neutrino yield from these complexes can increase. The estimated neutrino fluxes from the Orion nebula complex and the nucleus of the galaxy can be as high as 5⋅105 and 104 cm−2s−1, respectively, at the earth.
