Title: Evolution of Hub–Filament Structures in Star Formation
Speaker: Nanda Kumar (Instituto de Astrofísica e Ciências do Espaço, Universidade do Porto)
Abstract:
The hub–filament geometry of star-forming molecular gas is central to understanding several long-standing problems in star formation, ranging from the origin of massive stars to the possibility of a unified formation mechanism across the full stellar mass spectrum. The temporal evolution of this geometry also provides critical insight into key physical properties of the star-formation process. In this talk, I will address these issues using multi-wavelength observational data, with particular emphasis on recent JCMT/POL-2 observations of three star-forming regions.
