Dynamics in Star-forming Cores (DiSCo): project overview and the first look towards the B1 and NGC 1333 regions in Perseus
ABSTRACT The internal velocity structure within dense gaseous cores plays a crucial role in providing the initial conditions for star formation in molecular clouds. However, the kinematic properties of dense gas at core scales (∼0.01−0.1 pc) has not been extensively characterized because of instrume...

Our results suggest that a dense core’s internal velocity structure has little correlation with other core-scale properties, indicating these gas motions may be originated externally from cloud-scale turbulence. These first data sets also reaffirm the ability of GBT-Argus for studying dense core velocity structure and provided an empirical basis for future studies that address the angular momentum problem with a statistically broad sample.</description><identifier>ISSN: 0035-8711</identifier><identifier>EISSN: 1365-2966</identifier><identifier>DOI: 10.1093/mnras/stad3868</identifier><language>eng</language><publisher>United States: Oxford University Press</publisher><subject>ASTRONOMY AND ASTROPHYSICS ; formation of stars ; ISM ; kinematics and dynamics ; molecules ; protostars ; radio lines</subject><ispartof>Monthly notices of the Royal Astronomical Society, 2024-02, Vol.527 (4), p.10279-10293</ispartof><rights>2023 The Author(s).
