Resumen:
We present a study of the Serpens South cloud, which is part of the
CARMA Large Area Star-formation Survey (CLASSy) project. We observed a
210 square arcminute area of the Serpens South region, mapped at
7" resolution using the CARMA 23-dish mode in the HCN,
HCO+, and N2H+ J=1-0 emission lines.
The CARMA 23-dish mode combines simultaneous interferometric data from
the 3.5 m, 6.1 m, and 10 m antennas and autocorrelation spectra from the
10-m antennas to reconstruct full spatial images of the molecular
emission lines, tracing the structures from the large to small scales to
better understand how clouds evolve to form stars. Serpens South is
thought to be a very young star-forming region (a few 10E5 yr)
with a central cluster of protostars lying at the origin of a radial
filamentary structure. The CLASSy images allow us to analyze in detail
the spatial structure and gas kinematics of the central hub and the
substructure of the filaments. The northern 1 pc filament is clearly
resolved into a more collimated strips of gas. Its connection with the
central hub is not physically as clear as the connection of the
southwestern and southeast filaments. These filaments are also resolved
into several collimated structures, many of which are also velocity
separated given the high-spectral resolution of the CLASSy data (0.15
km/s).
