Gamma-rays, neutrinos and cosmic rays from dense regions in open clusters

We analyse the high energy processes, occurring within open clusters containing massive binary systems, which turn to the production of high energy γ-rays and neutrinos. Nuclei, accelerated within the binary systems, inject protons and neutrons as a result of their fragmentation in collisions with stellar radiation and matter of the winds. We calculate the radiation produced by these protons and neutrons during their interaction with the matter of the stellar wind and the open cluster. The detectability of γ-ray emission and neutrino emission by the present and future Cherenkov telescopes and the neutrino telescopes is discussed.
