Observational study of high-mass star formation at the junction of filaments
Speaker: Kshitiz Mallick
Abstract:
Understanding high-mass star formation is an important pillar of astronomical research, due to the large impact of such sources on their natal environment. Various paradigms have been proposed for the formation of such stellar sources, with hub filament systems (HFS) having emerged as an important contender for understanding not only how massive stars form, but also the evolution of a molecular cloud as it collapses and fragments to form stars. In this talk, I present the results of my recent observational analysis of some high-mass star forming regions, carried out using molecular data cubes, complemented by other multiwavelength data. We discuss the complex nature of such star forming regions, the conundrums faced in analysis of hubs and filamentary structures, and the further work one needs to undertake to fully comprehend the connection between (high-mass) star formation and HFS.
