Hot 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 ...
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 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 کاملProbing the inner 200 AU of low-mass protostars with the Submillimeter Array: Dust and organic molecules in NGC 1333-IRAS2A
The Submillimeter Array has opened a new window to study the innermost warm and dense regions of the envelopes and disks around deeply embedded protostars. This paper presents high-angular resolution (< 2) submillimeter observations of the class 0 young stellar object NGC 1333-IRAS2A. Dust continuum emission and lines of complex organic molecules such as CH3OCH3 and CH3OCHO, high excitation CH3...
