Carma 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 کاملSio Observations of the Ngc 1333 Iras 2a Protostellar Jet
We present 86.8 GHz SiO J=2-1 observations of the molecular outflow from the protostellar source NGC 1333 IRAS 2A. Silicon monoxide is a sensitive tracer of shocks in molecular gas, and the emission clearly traces terminal bow-shocks at the ends of the outflow lobes, as well as emission knots and a source coincident with the protostar. Our three-field mosaic from the BIMA interferometer covers ...
متن کاملThe 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 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 کاملModeling the magnetic field in the protostellar source NGC 1333 IRAS 4 A
Context. Magnetic fields are believed to play a crucial role in the process of star formation. Aims. We compare high-angular resolution observations of the submillimeter polarized emission of NGC 1333 IRAS 4A, tracing the magnetic field around a low-mass protostar, with models of the collapse of magnetized molecular cloud cores. Methods. Assuming a uniform dust alignment efficiency, we computed...
