| Popis: | The AGILE satellite is observing the $$\gamma $$-ray sky since its launch on April 23, 2007. Several important discoveries have been made in Galactic and extragalactic astrophysics starting from its observations above 50 MeV. In this work, I reviewed the most important findings in the study of $$\gamma $$-ray emitting Galactic binary systems: the first detection above 100 MeV of Cygnus X-1, the discovery of $$\gamma $$-ray transient emission from Cygnus X-3, the first observation of a colliding wind binary in $$\gamma $$ rays. The AGILE continuous monitoring of the $$\gamma $$-ray sky is a fundamental ingredient to investigate the non-thermal emission from these sources, the disk-jet coupling, the limit of relativistic particle acceleration in the jet, the origin of the high-energy $$\gamma $$-ray radiation. |
