The molecular outflows in NGC 1333
We present the results of CO(J =3→2) mapping using the James Clerk Maxwell Telescope of the active star formation region NGC 1333, supplemented by CO(J=1→0) mapping from the Onsala Space Observatory millimetre telescope. These maps provide a detailed overview of the complex cluster of overlapping molecular outflows associated with Herbig-Haro (HH) objects and shocked H2, and the far-infrared an...
متن کاملCores and cavities in NGC 1333
We present 1.3mm continuum and CS J = 5 → 4 maps at 12′′ resolution of the NGC1333 star forming region. The area covered is 8′ × 6′. The large-scale bolometer and CS maps delineate very nicely the large central cavity together with the cores situated in the surrounding compressed shell. In addition to the four dust cores IRAS4A-B, IRAS2 and SVS13, we discovered two fainter condensations, one of...
متن کاملCarma Observations of Protostellar Outflows in Ngc 1333
We present observations of outflows in the star-forming region NGC 1333 using the Combined Array for Research in Millimeter-Wave Astronomy (CARMA). We combined the CO and CO (10) CARMA mosaics with data from the 14-m Five College Radio Astronomy Observatory (FCRAO) to probe the central, most dense and active region of this protostellar cluster at scales from 5′′ to 7′ (or 1000 AU to 0.5 pc at a...
متن کاملObservations of Global and Local Infall in NGC 1333 Andrew
We report “infall asymmetry” in the HCO (1–0) and (3–2) lines toward NGC1333, extended over ∼ 0.39 pc, a larger extent than has been reported before, for any star-forming region. The infall asymmetry extends over a major portion of the star-forming complex, and is not limited to a single protostar, or to a single dense core, or to a single spectral line. It seems likely that the infall asymmetr...
متن کاملNear - Infrared Spectroscopy of Molecular Hydrogen Emission in Four Reflection Nebulae : NGC 1333 , NGC 2023 , NGC 2068 , and NGC 7023
We present near-infrared spectroscopy of fluorescent molecular hydrogen (H2) emission from NGC 1333, NGC 2023, NGC 2068, and NGC 7023 and derive the physical properties of the molecular material in these reflection nebulae. Our observations of NGC 2023 and NGC 7023 and the physical parameters we derive for these nebulae are in good agreement with previous studies. Both NGC 1333 and NGC 2068 hav...
