The H 2 structure of OMC – 1 ?
We have obtained narrow-band images of the Orion Molecular Cloud OMC–1 in various infrared transitions of molecular hydrogen. The molecular emission from levels with low excitation energies (<∼ 15 000K) is made up of numerous linear, jet–like structures. Their collimation factor is typically about 10 and there is no appreciable outward broadening. Most of these structures are arranged radially ...
متن کامل17μm molecular hydrogen line emission from OMC-1
The v=0-0 S(1) line of molecular hydrogen at 17.03μm has been measured in the source OMC-1 along a 90′′ cut passing through the near-IRH2 emission Peaks 1 and 2 using the Kuiper Airborne Observatory. The line flux is typically 50% of the 2.12μm v=1-0 S(1) line, but its distribution is somewhat more extended and it is relatively brighter at Peak 2.We interpret this as shocked emission coming fro...

متن کاملThe stellar content of OMC 2 / 3 ⋆
We have revisited the stellar content of OMC 2 and OMC 3 by means of MIR imaging and NIR photometry; in addition, we have extended the existing (sub)mm maps by a huge 1200 μm map obtained with SIMBA showing new sources and filamentary features for the first time at that wavelength. The MIR data reveal 43 new sources at N and Q which are partly associated with dense condensations at millimetre w...
متن کاملMolecular Hydrogen Polarization Images of Omc{1
A polarization image, with 0.6" pixel scale, of the molecular hydrogen v=1{0 S(1) line at 2.1218 m in the core of the Orion Molecular Cloud One, is presented. The line emission is highly clumped, with a prominent lamentary structure protruding to the NW, away from the source of the out ow. There are two main characteristics of the line polarization; a region of aligned vectors over the the mole...
