Detection of a hot core in the intermediate - mass Class 0 protostar NGC 7129 – FIRS 2

the date of receipt and acceptance should be inserted later Abstract. We report high angular resolution (HPBW∼ 0.6 ′′ × 0.5 ′′ at 1.3mm) observations of the Class 0 intermediate-mass (IM) protostar NGC 7129–FIRS 2 using the Plateau de Bure Interferometer. Our observations show the existence of an intense unresolved source in the continuum at 1.3mm and 3mm at the position of the Class 0 object. ...

Strongly induced collapse in the Class 0 protostar NGC 1333 IRAS 4 A

Context. The onset of gravitational collapse in cluster-forming clouds is still poorly known. Aims. Our goal is to use the Class 0 protostar IRAS 4A, which is undergoing collapse in the active molecular cloud NGC 1333, to set constraints on this process. In particular we want to measure the mass infall rate and investigate whether the collapse could have been triggered by a strong external pert...

Is the Cepheus E Outflow driven by a Class 0 Protostar ?

New early release observations of the Cepheus E outflow and its embedded source, obtained with the Spitzer Space Telescope, are presented. We show the driving source is detected in all 4 IRAC bands, which suggests that traditional Class 0 classification, although essentially correct, needs to accommodate the new high sensitivity infrared arrays and their ability to detected deeply embedded sour...

Discovery of X Rays from Class 0 Protostar Candidates in Omc-3

We have observed the Orion Molecular Clouds 2 and 3 (OMC-2 and OMC-3) with the Chandra X-ray Observatory (CXO). The northern part of OMC-3 is found to be particularly rich in new X-ray features; four hard X-ray sources are located in and along the filament of cloud cores. Two sources coincide positionally with the submm-mm dust condensations of MMS 2 and 3 or an outflow radio source VLA 1, whic...

L 483 : a protostar in transition from Class 0 to Class I

We present line observations of different molecular species toward the dense core in L483 and its bipolar outflow powered by the Class 0 object IRAS 181480440. CO(2–1) maps show that the outflow is well collimated and asymmetric, and that its gas is warmer than the surrounding cloud by at least a factor of 2. In contrast with the outflows from other Class 0 objects, the CH3OH(2k–1k) lines in L4...
