Star formation in collapsing proto-clusters
DSI, Stuttgart, DE
|Infall signatures (red shifted absorption of NH3 rotational transitions) of neutral gas onto bright dust continuum clumps have been detected with SOFIA GREAT at 1.81 THz in a number of cases in APEX/ATLASGAL GPS sources. High accretion rates of the order of 10-3 Msol/yr have been derived. This new observational techniques holds great promise for understanding the early phases of clustered star formation. Follow-up high spatial resolution submm imaging of these proto-clusters is now needed to study the fragmentation process into low- and high-mass proto-stars.
