OB runaway stars originating in the Vel OB1 association
N. Azatyan, L. Kaper, A. Samsonyan +4
OB runaway stars are massive stars moving through interstellar space at high velocities (up to 200 km/s), produced by dynamical ejections in young massive clusters or supernova exp…
IdentYS: A Python-Based Tool for Identifying Young Stars in Star-Forming Regions
E. Nikoghosyan, D. Baghdasaryan, D. Andreasyan +3
Research on young stellar populations is essential to understand the properties of embedded clusters and advance theories of their formation. This has driven advancements in method…
The runaway nature and origin of α Crucis system
M. Torosyan, N. Azatyan, E. Nikoghosyan +2
Massive stars are always the focus of astronomical research and a significant part of them (10--20%) moves in space at a high (supersonic) velocity. This paper presents the results…
Searching for stellar population in the molecular cloud GRSMC 045.49+00.04
N. Azatyan, E. Nikoghosyan, A. Samsonyan +5
Understanding the characteristics of young stellar populations is essential for deriving insights into star formation processes within parent molecular clouds and the influence of…
Infrared study of the star-forming region associated with the UC HII regions G45.07+0.13 and G45.12+0.13
Naira Azatyan, Elena Nikoghosyan, Hayk Harutyunian +2
UCHII regions are an important phase in the formation and early evolution of massive stars and a key component of the interstellar medium. The main objectives of this work are to s…
Structure of IRAS 05168+3634 star-forming region
E. H. Nikoghosyan, N. M. Azatyan, D. H. Andreasyan +1
This study aims to determine the main physical parameters (N(H2) hydrogen column density and Td dust temperature) of the Interstellar medium, and their distribution in the extended…
Variability of Ha emission in young stellar objects in the cluster IC 348
Elena H. Nikoghosyan, N. M. Azatyan
The aim of this work is to identify and study the stellar objects with variable EW(Ha) in the young stellar cluster IC 348. We performed photometric and slit-less observations at s…
New eruptive variable in the massive star-forming region associated with IRAS 18507+0121 source
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…
The search of the stellar clusters in vicinity of YSOs with high and middle masses
N. M. Azatyan, E. H. Nikoghosyan
The results of the searching on the bases of GPS UKIDSS survey's data of dense compact stellar clusters in the vicinity of 20 YSOs with high and middle masses are presented. Totall…
