CARMA LARGE AREA STAR FORMATION SURVEY: PROJECT OVERVIEW WITH ANALYSIS OF DENSE GAS STRUCTURE AND KINEMATICS IN BARNARD 1
We present details of the CARMA Large Area Star Formation Survey (CLASSy), while focusing on observations of Barnard 1. CLASSy is a CARMA Key Project that spectrally imaged N sub(2)H super(+) HCO super(+), and HCN (J = 1 arrow right 0 transitions) across over 800 square arcminutes of the Perseus and...

description | We present details of the CARMA Large Area Star Formation Survey (CLASSy), while focusing on observations of Barnard 1. CLASSy is a CARMA Key Project that spectrally imaged N sub(2)H super(+) HCO super(+), and HCN (J = 1 arrow right 0 transitions) across over 800 square arcminutes of the Perseus and Serpens Molecular Clouds. N sub(2)H super(+) shows the strongest emission, with morphology similar to cool dust in the region, while HCO super(+) and HCN trace several molecular outflows from a collection of protostars in the main core. We identify a range of kinematic complexity, with N sub(2)H super(+) velocity dispersions ranging from ~0.05 to 0.50 km s super(-1) across the field. Comparing these relations, we propose that all dense gas structures in Barnard 1 have comparable depths into the sky, around 0.1-0.2 pc; this suggests that overdense, parsec-scale regions within molecular clouds are better described as flattened structures rather than spherical collections of gas. Science-ready PPV cubes for Barnard 1 molecular emission are available for download. |
