Task Description and Goals

The formation of star cluster is a topic of considerable interest since most stars in our Galaxy form in groups within clustered environments. In addition, more than 70% of the prestellar cores are identified within filaments of dense molecular gas. Several environmental conditions can breed the young clusters, such as fragmentation of the swept-up matter in the shells of the expanding HII regions, matter at the collision point of molecular clouds, matter at the junction of converging filaments or the hub of filamentary systems. The initial cloud configuration also decides the future location of cluster formation. Therefore, the exact role of environment on the star and star cluster formation of a cloud can only be thoroughly understood by tracing various components of the interstellar medium through multiwavelength observations. In this project, we will investigate the kinematics of a filamentary structure associated with a young cluster using CO molecular data. Along with kinematics of the filaments and the distribution of ionized, molecular gas and protostars, we will try to explore the likely mechanism of cluster formation in that filament.
