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 of a study of the $\alpha$ Crucis system, located at $\sim$114 pc dis

Understanding the characteristics of young stellar populations is essential for deriving insights into star formation processes within parent molecular clouds and the influence of massive stars. This study focuses on YSOs in the G 045.49+00.04 molecu

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 star-forming region, which includes IRAS 05156+3643, 05162+3639, 0516

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 several epochs in order to reveal the variable objects. Significant var
