Vla Observations of Water Maser Emission Associated with Svs 13 and Other Sources in Ngc 1333
The young stellar object SVS 13 is believed to power the chain formed by the HH 7-11 objects. Recent observations have revealed that in the radio continuum (3.6-cm) the source is a binary with components separated by about 0. 00 3 in the east-west direction. The members of the binary are named VLA 4A (western component) and VLA 4B (eastern component). In an attempt to ascertain which of the two...
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 کاملWater emission in NGC 1333 - IRAS 4 ⋆ The physical structure of the envelope
We report ISO-LWS far infrared observations of CO, water and oxygen lines towards the protobinary system IRAS4 in the NGC1333 cloud. We detected several water, OH, CO rotational lines, and two [OI] and [CII] fine structure lines. Given the relatively poor spectral and spatial resolution of these observations, assessing the origin of the observed emission is not straightforward. In this paper, w...
