Abstract:
It is now widely accepted that interstellar filaments represent a key intermediate stage in the star formation process. The vast majority of cores, the direct progenitors of stars, sit on top of the densest filaments. Yet a number of questions remain regarding the physics that govern their evolution and fragmentation. Only the detailed study of the early stages of cloud evolution can help shed light on the exact role of filaments in 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 morphology, containing 4 parsec-long filaments that spatially converge on a central hub region. Containing 1000M of material, it is classed as an intermediate to high mass star forming region. Overall, SDC13 is an ideal target to study how filaments form, fragment and dynamically interact with each other.
