TL;DR
This study uses high-resolution ALMA observations to analyze the masses and spatial distribution of protostars in Serpens South, revealing primordial mass segregation and clustering in a young low-mass star-forming region.
Contribution
First ALMA-based detailed analysis of protostellar mass distribution and spatial segregation in Serpens South, demonstrating primordial mass segregation in a low-mass cluster.
Findings
Detected 52 protostellar sources with masses 0.002-0.9 solar masses.
Evidence of primordial mass segregation and clustering.
Higher-mass sources are concentrated near dense gas regions.
Abstract
Aims: We investigated the masses and spatial distributions of pre-stellar and protostellar candidates in the young, low-mass star forming region Serpens South, where active star formation is known to occur along a predominant filamentary structure. Previous observations used to study these distributions have been limited by two important observational factors: (1) sensitivity limits that leave the lowest-mass sources undetected, or (2) resolution limits that cannot distinguish binaries and/or cluster members in close proximity. Methods: Recent millimeter-wavelength interferometry observations can now uncover faint and/or compact sources in order to study a more complete population of protostars, especially in nearby ( pc) clusters. Here we present ALMA observations of 1 mm (Band 6) continuum in a arcminutes region at the center of Serpens South. Our angular…
