SPECTRAL ANALYSIS OF YSOs AND OTHER EMISSION-LINE STARS IN THE NORTH AMERICA AND PELICAN NEBULAE REGION
Far red spectra for 34 stars with V magnitudes between 15 and 18 in the direction of the North America and Pelican nebulae (NAP) star-forming region are obtained. Some of these stars were known earlier as emission-line objects, others were suspected as pre-main-sequence stars from photometry in the J, H, Ks and Vilnius systems. We confirm the presence of the Hline emission in the spectra of 19 stars, some of them exhibit also emission in the OI and CaII lines. In some of the stars the Habsorption line is filled with emission. To estimate their evolutionary status, the spectral energy distribu- tions, based on Vilnius, 2MASS, MSX and Spitzer photometry, are applied. Only eight emission-line stars are found to be located at a distance of the NAP complex. Others are either chromospherically active stars in front of the com- plex or distant luminous stars with Habsorption and emission components. For five stars with faint emission the data are not sufficient toestimate their distance. One star is found to be a heavily reddened K-supergiant located in the Outer arm. The stars, for which we failed to confirm the emission in H�, are mostly red dwarfs located in front of the NAP complex, two of them could be binaries with L-type components. Taking into account the stars suspected to be YSOs by their 2MASS colors we conclude that the NAP complex can possess a considerable population of young stars hidden behind the dust cloud.
