Description
Cloud-cloud collision (CCC) is one of the proposed mechanisms that explain how massive stars acquire their mass. We investigate the dense interface of the CCC candidate G323.18+0.15, where two velocity components separated by ~2.6 km/s converge, and determine how the collision has triggered core and star formation. Using ALMA Band 6 dust continuum and molecular-line observations, we have characterized the filamentary structure and its fragmentation. The continuum emission resolves a filament that breaks into nine dense cores with masses of range of 0.9–6 solar masses. Molecular lines reveal bipolar outflows toward four of these cores, indicating active star formation. These results suggest that the collision has facilitated fragmentation and early star formation, supporting CCCs as a large-scale mechanism for massive star formation.
