Characterisation of filaments hubs in Orion
Andrea Socci FGGA, Vienna, AT | |
| Orion is the closest intermediate-/high-mass stellar nursery to the Sun, therefore is a great laboratory to study the formation of these fast evolving and deeply embedded high-mass protostars. Their observations are scarce and their formation pathways still under debate, but the study of associations of filaments (hubs) in molecular clouds can possibly answer the high-mass star-formation question: their intersections result in high-density condensations possibly collapsing into a cluster with at least one massive object. This study aims to characterise velocity-coherent filaments into 7 hub-like structures along the Orion A & B clouds, including low-, intermediate- and high-mass star-forming regions, all observed with ALMA at high spatial and spectral resolutions. The different environmental conditions and mass reservoirs of these regions significantly affect the main physical properties, such as length, mass, width, of the filaments identified in them. We statistically investigated and compared these properties to have new insights on how the gas flows from the parental cloud through filaments into the compact cores and if the environment has a substantial impact on this process. | |
