Emergence of low- and high-mass stars in complex fiber networks

Abstract: The filamentary nature of the Interstellar Medium plays a fundamental role on the star formation process. Filaments dominate the gas structure inside molecular clouds and promote the formation of stars in them, from low-mass stars formed in isolated filaments to high-mass objects found in hub-filament associations. Still, the origin and evolution of these different gas structures are matter of strong debates. Recent high resolution studies highlighted the complex gas kinematics inside filamentary regions, typically exhibiting a rich hierarchical structure of sub-filaments (or fibers) forming densely populated networks. During my talk I will discuss how both low- and high-mass star formation regimes can naturally emerge in fiber networks of different complexity paving the way for a unified scenario of star formation.
