Abstract
One of the most prominent features of young objects in the optical range is the presence of emission lines, in particular Ha at 6563A. Therefore, Ha emission is the most common spectroscopic means for identifying young stars. We present the search's results of PMS stellar objects in the several star forming regions carried out on 2.6 m telescope in Byurakan observatory. We have used the method of slit-less spectroscopy employing a grism in combination with a narrow-band Ha interference filter to detect the objects with Ha emission.
