Binary systems in which one of the components is a massive star and the companion is either a similar star or a compact object; present non-thermal emission from radio to X- and -rays. The main goal of this work is to characterize the high-energy physics of gamma-ray binaries by implementing a general modeling for their most important high-energy processes. Specifically; we calculated the spectral energy distribution for emitters located in different positions of the binary system; which allowed to study the impact of the geometry in the resulting emission from the source. This was done for different cuts of the relevant state parameters. Finally; we used this procedure to produce emissivity maps which are an useful tool for exploring statiscal properties of gamma-ray binaries as well as their expected distribution in the galaxy.
