We present the results of the investigation of ISM and the young stellar population in the IRAS 18316-0602 star-forming region which is referred to as UCHII (G25.65+1.05). Single temperature modified blackbody model shows that values of N(H2) hydrogen column density and Td dust temperature are in ranges 2 - 7x1023 cm-2 and 12 - 30 K, respectively. The analysis of infrared photometric data allowed to reveal about 50 young stellar objects in the G25.65+1.05 UCHII region.

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.
