Abstract
Massive Wolf-Rayet stars in a compact binary systems are characterised by very strong winds which collide creating a shock wave. If the wind nuclei accelerated at the shock can reach large enough energies, they suffer disintegration in collisions with soft thermal radiation from the massive stars injecting relativistic protons and neutrons. Protons collide with the matter of the wind and a fraction of neutrons colide with the massive stars producing gamma-rays and neutrinos. We calculate the gamma-rays fluxes from the inverse Compton pair cascades, initiated by primary gamma-rays and leptons produced by protons, and the neutrino fluxes produced by protons and ne...
