High angular resolution observations towards OMC-2 FIR 4: Dissecting an intermediate-mass protocluster

Context. Intermediate-mass stars are an important ingredient of our Galaxy and key to understand how highand low-mass stars form in clusters. One of the closest known young intermediate-mass protoclusters is OMC-2 FIR 4, located at a distance of 420 pc, in Orion. This region is one of the few where the complete 500-2000 GHz spectrum has been observed with the heterodyne spectrometer HIFI on boa...

On the Nature of the Deeply Embedded Protostar Omc-2 Fir 4

We use mid-infrared to submillimeter data from the Spitzer, Herschel, and APEX telescopes to study the bright sub-mm source OMC-2 FIR 4. We find a point source at 8, 24, and 70 μm, and a compact, but extended source at 160, 350, and 870 μm. The peak of the emission from 8 to 70 μm, attributed to the protostar associated with FIR 4, is displaced relative to the peak of the extended emission; the...

Magnetic Fields in Star-Forming Molecular Clouds I. The First Polarimetry of OMC-3 in Orion A

The first polarimetric images of the OMC-3 region of the Orion A filamentary molecular cloud are presented. Using the new imaging polarimeter on SCUBA at the James Clerk Maxwell Telescope, we have detected polarized thermal emission at 850 μm from dust along a 6 length of the dense filament. The polarization pattern is highly ordered and is aligned with the long axis of the filament throughout ...

Millimeter- and Submillimeter-Wave Observations of the OMC-2/3 Region. III. An Extensive Survey for Molecular Outflows

Using the ASTE 10 m submillimeter telescope and the 1.4 m Infrared Survey Facility (IRSF), we performed an extensive outflow survey in the Orion Molecular Cloud -2 and -3 region. Our survey, which includes 41 potential star-forming sites, has been newly compiled using multi-wavelength data based on millimeterand submillimeter-continuum observations as well as radio continuum observations. From ...

Simulations of ionisation triggering

We review recent pilot simulations that incorporate feedback from ionising radiation in SPH calculations of star forming clouds. In the case that the ionising radiation source is located within the star forming cloud, the inhomogeneity of the cloud significantly modifies the way that feedback operates compared with spherically symmetric cloud models. Inflow/outflow behaviour develops, combining...
