The Cygnus region of the sky hosts different types of radio-emitting sources, such as supernovaremnants, binary stellar systems, protoplanetary disk-like sources, and is also a very rich area in young stellarobjects. These objects, evidences of the first stages of star formation, are classified into types according to theirevolutionary stage, following their spectral index in the infrared. Using the Giant Metrewave Radio Telescope(GMRT), an area of ∼ 10 deg 2 of Cygnus was surveyed in two bands. The region contais ≈ 730 young stellarobjects, mostly in the association of Cygnus OB2, of which 22 were detected in radio waves. We present preliminaryresults of a study of the emission detected with the GMRT at the position of these objects, especifically theirradio flux density spectral index, in order to unveil physical processes acting on them.
