E. H. Nikoghosyan, N. M. Azatyan, K. G. Khachatryan
Aims. We report the discovery of a strong outburst of the embedded young stellar object (YSO), namely UKIDSS-J185318.36+012454.5, located in the star-forming region associated with…
Search for Compact Stellar Groups in the Vicinity of IRAS Sources
N. M. Azatyan, E. H. Nikoghosyan, K. G. Khachatryan
The results of a search for compact clusters in the vicinity of 19 IRAS sources based on data from the GPS UKIDSS and Spitzer GLIMPSE surveys are presented. Overall, clusters have…
The search and study of PMS stars with Ha emission
E. H. Nikoghosyan, A. V. Vardanyan, K. G. Khachatryan
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 spe…
