X-ray and γ-ray spectra expected for the model A (left) and model B (right) at the periastron passage of the stars in the binary system Eta Carinae compared with the high-energy observations of this system. The measurements in the hard X-rays by the INTEGRAL satellite (Leyder et al. 2010) are marked by squares and those in the γ-ray energy range by the Fermi-LAT detector (Farnier et al. 2010; Abdo et al. 2010) are marked by triangles. The results of the calculations are shown for the model A (left panel): γ-rays from electrons accelerated at the shock from the side of the Eta Carinae star (solid) and from electrons accelerated at the shock from the side of the companion star: without any absorption (thin dashed), with absorption for the γ-ray propagating at the angle equal to 50^o (towards the star) at distance from the star D = 1.4R_EC (dashed), and at the same angle but for the parts of the shock at the distance from the star D = 10R_EC (dot-dashed). For Model B (right panel): γ-rays from electrons, accelerated at the shock from the side of the Eta Carinae star, scattering stellar radiation in the T regime (solid), γ-rays from decay of neutral pions produced by hadrons accelerated at the shock from the side of the Eta Carinae star: unabsorbed spectrum (thin dashed curve extending to lower energies), spectra absorbed in the stellar radiation for distances from the star: D = 1.4R_EC (thick dashed) and D = 10R_EC (dot-dashed). Secondary leptons from decay of charged pions (produced in hadronic collisions) lose energy on the synchrotron radiation (dot-dot-dashed curve). The γ-ray spectrum produced by hadrons, which are accelerated at the shock from the side of the companion star and produce pions in the interactions within the Eta Carinae nebula, are shown by the thin dashed curve extending to higher energies.
