ALMA Reveals Kinematics of Super Star Cluster Candidate H72.97-69.39 in LMC-N79

Abstract

Conditions in super star clusters (SSCs) lead to the formation of dozens of massive stars in close proximity. However, SSCs are rare in the local universe. H72.97-69.39, located in the N79 region of the Large Magellanic Cloud (LMC), is an SSC candidate. In this paper we report the ALMA observations of the potential SSC. ALMA reveals colliding filaments, outflows, an H ii region, and a C ii region associated with this cluster. The timescale of the outflow is 65,000 yr, which is consistent with this being a young cluster. The molecular gas around this potential early-stage SSC candidate is complex in nature on small scales (as seen with ALMA) and large scales (as seen with Herschel ).
