Star Formation Studies at ARIES and Related Instrumentation

Hub-filament systems (HFSs), the key structures in molecular clouds, play a central role in star formation, particularly in the birth of massive stars and star clusters. Massive OB stars continuously emit radiative and mechanical energy, significantly shaping the surrounding environment. However, despite their dominant impact, the processes underlying their origin and feedback remain poorly understood and are active research areas. The availability of highly sensitive/resolved multi-wavelength data from various telescopes/ instruments recently provides an unprecedented opportunity to look deeper into the details of the unexplored sites of various Galactic star-forming regions, both on small scales (AUs) and large scales (parsecs). In this talk, I will present our recent results from the study on those regions, which help constrain different star formation scenarios/models.


The 3.6m Devasthal Optical Telescope (DOT) with active optics technology has been installed at Devasthal, Nainital. It is used for optical and near-infrared (photometric and spectroscopic) studies of various astronomical topics. In this talk, I will also present an overview of this facility along with key science results.
