Abstract

The SPIRE and PACS images from the Gould Belt key program observed by Herschel reveal fascinating, omnipresent filamentary structures as well as numerous dense cores embedded in the filaments (André et al. 2010).
I will present some preliminary analysis of the radial profiles of the filaments present in three fields observed with Herschel: Aquila rift, Polaris flare and IC 5146. This study coming from the observed properties (length, width, column density, critical line mass) of the filaments enables us to constrain the theories (gravitational collapse, cloud turbulence, magnetic field) on the formation of the filaments in star forming regions.
