The formation and evolution of protostars and their cluster environment are topics whose study utilizes the sensitivity, angular and spectral resolution, and mapping capabilities recently provided with ALMA. Serpens South is a young protostellar cluster that caught attention upon its discovery in Spitzer IRAC observations for the following reasons: (1) a high protostar fraction that indicates very recent and ongoing star formation; (2) iconic clustered star formation along a filamentary structure; (3) its relative proximity within a few hundred parsecs. In this talk I will present a multi-faceted ALMA data set, including maps of millimeter-wave continuum sources and molecular outflows throughout the region, as well as a more focused kinematical study of the protostar that is the strongest continuum source at the cluster center. Currently, we focus on the 52 protostar candidates detected near the cluster center, many of which are deeply embedded sources that could not be detected with Spitzer IRAC, and/or low-flux (low-mass) sources never before detected in mm-wavelengths. We find evidence of mass segregation and clustering according to the Minimum Spanning Tree method, distribution of projected separations between unique sources, and concentration of higher-mass sources near to the dense gas at the cluster center. Given the young age of this cluster, the mass segregation is likely primordial.
Unless announced otherwise, the lunch talks start at 12:30 sharp. The approximate duration of the lunch talk is given above, and additional time will be given for questions and discussion following the presentation. Please make sure that you take ample time to pick up your lunch beforehand.
Information for Speakers and Hosts: Talks by internal speakers are limited to 20 minutes, with additional time for questions. Visiting speakers can have up to 30 minutes, with additional time for questions. Hosts are responsible for bringing the speaker to the correct room in ample time to set up laptops etc., and for ensuring the speaker also has time for lunch.
