Our research focuses on the stellar content of two star-forming regions. The first one is the molecular cloud which includes G45.12+0.13 and G45.07+0.13 UCHII regions around IRAS 19111+1048 and 19110+1045 sources, respectively. Based on infrared photometric data, we identified a rich stellar population, which includes 909 YSOs with different evolutionary stages. Among selected YSOs there are ZAMS objects. The second one is an elongated molecular cloud, which includes IRAS 05184+3635, 05177+3636, 05168+3634, 05162+3639, and 05156+3643 sources. We identified 1224 candidates of YSOs in the molecular cloud with different evolutionary stages. Selected YSOs are mostly younger then 0.1Myr. The distribution of selected YSOs in both star-forming regions shows that there are dense clusters in the vicinity of all IRAS sources.

Communications of the Byurakan Astrophysical Observatory (ComBAO) is a peer-reviewed scientific journal, which publishes research in observational and theoretical astronomy/astrophysics and presents recent advances in these fields. It is being published by the NAS RA V. Ambartsumian Byurakan Astrophysical Observatory (BAO) in English in electronic form. The journal publishes original papers, review papers, brief reports, book reviews, special communications, observational and theoretical results in various fields of astronomy and related sciences, and some editorial notes, including anniversaries and obituaries. Under the heading “Legacy”, the renewed magazine will republish some old articles of high value in English. The heading “Guest articles” will bring to the attention of readers the articles of researchers who are not employees of BAO. ComBAO was founded in 1946 and regularly published in 1946-1990. However, the publication was interrupted because of the economic situation after the disintegration of the Soviet Union in 1991.
