Sio 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 impact of shocks on the chemistry of molecular clouds High resolution images of chemical differentiation along the NGC 1333–IRAS 2A outflow
This paper presents a detailed study of the chemistry in the outflow associated with the low-mass protostar NGC 1333–IRAS 2A down to 3′′ (650 AU) scales. Millimeter-wavelength aperture-synthesis observations from the Owens Valley and Berkeley-Illinois-Maryland-Association interferometers and (sub)millimeter single-dish observations from the Onsala Space Observatory 20 m telescope and Caltech Su...
متن کاملAn S - shaped outflow from IRAS 03256 + 3055 in NGC 1333
The IRAS source 03256+3055 in the NGC 1333 star forming region is associated with extended sub-millimeter emission of complex morphology, showing multiple clumps. One of these is found to coincide with the driving source of a bipolar jet of S-shaped morphology seen in the emission lines of Hα and [SII] as well as in the H2 emission lines in the K-band. Detailed images of the driving source at t...
متن کاملA molecular line study of NGC 1333/IRAS 4.
Molecular line surveys and fully sampled spectral line maps at 1.3 and 0.87 mm are used to examine the physical and chemical characteristics of the extreme Class I sources IRAS 4A and 4B in the L1450/NGC 1333 molecular cloud complex. A very well collimated, jetlike molecular outflow emanates from IRAS 4A, with a dynamical age of a few thousand years. Symmetric, clumpy structure along the outf...
متن کاملHot corinos in NGC 1333 - IRAS 4 B and IRAS 2 A
Context. Complex organic molecules have been detected in massive hot cores for over two decades, and only recently in three hot corinos (the inner regions surrounding Sun-like protostars, where the dust temperature exceeds 100 K). Since hot corinos have sizes of ∼100 AU (i.e., of the order of the extent of the Solar System), it is particularly relevant to understand whether they are common and ...
