Resum

Jets are possibly the most spectacular and powerful phenomena in astrophysics. They are ubiquitous in the universe, common to a number of different accreting objects, from non-relativistic to relativistic systems, such as young stellar objects, cataclysmic variables, X-ray binaries and active galactic nuclei. However, the mechanism(s) of jet production is still poorly understood. In the search for the elements and parameters contributing to the formation of jets, key is the cross comparison of the different jet systems. The accretion disk is a common denominator for all these sources and seems to be essential to the formation of their jets. However, differences in the jet behaviour among these systems, indicate that also parameters proper of the accreting star might play a role in the jet production. I will give an overview of our observational knowledge of jets through studies of X-ray binaries.
