Searches for HH-objects and emission stars in star-formation regions. VIII. Stars with Hα emission in the vicinity of the nebula GM 2-41
Abstract
43 stellar objects with Hα emission are discovered by slitless spectroscopy in a 14' × 14' area near the nebula GM 2-41 located in the HII region DR 15 at the southern edge of the Cyg OB2 association. Emission is detected for the first time for 30 of these objects. Based on VI and JHK photometric data, the overwhelming majority of these objects are classified as young stellar objects in spectral classes F7-M3 with ages of ~1 Myr. The stars are distributed nonuniformly and form two groups which have the same coordinates as the UCHII regions G0.79 + 0.3 and G79.2 + 0.4.
