Abstract

It is now widely accepted that interstellar filaments represent a key intermediate stagein the star formation process. The vast majority of cores, the direct progenitors ofstars, sit on top of the densest filaments. Yet a number of questions remain regardingthe physics that govern their evolution and fragmentation. Only the detailed studyof the early stages of cloud evolution can help shed light on the exact role of filamentsin the star formation process. This is the purpose of this thesis.I present a study of the SDC13 infrared dark cloud hub filament system.SDC13 resides 3.6±0.4 kpc away in the galactic plane, and has a remarkable mor-phology, containing 4 parsec-long filaments that spatially converge on a central hubregion. Containing 1000Mof material, it is classed as an intermediate to high massstar forming region. Overall, SDC13 is an ideal target to study how filaments form,fragment and dynamically interact with each other.
