A Large Scale Survey of NGC 1333 Andrew
We observed the clustered star forming complex NGC1333 with the BIMA and FCRAO telescopes in the transitions HCO(1–0) and N2H (1–0) over an 11 × 11 area with resolution ∼ 10 (0.015 pc). The N2H emission follows very closely the submillimeter dust continuum emission, while HCO emission appears more spatially extended and also traces outflows. We have identified 93 N2H + cores using the CLUMPFIND...
متن کاملThe structure of the NGC 1333 - IRAS 2 protostellar system on 500 AU scales
This paper investigates small-scale (500 AU) structures of dense gas and dust around the low-mass protostellar binary NGC 1333-IRAS2 using millimeter-wavelength aperture-synthesis observations from the Owens Valley and BerkeleyIllinois-Maryland-Association interferometers. The detected λ = 3 mm continuum emission from cold dust is consistent with models of the envelope around IRAS2A, based on p...
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 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 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 ...
