OSSE observations of the Orion giant molecular cloud during 1996
نویسندگان
چکیده
We have combined all OSSE spectra of the Orion molecular cloud complex obtained through the end of 1996 and searched them for evidence of cosmic-ray induced γ-ray lines in the 3–7 MeV energy range, as detected by COMP-TEL (Bloemen et al. 1994, 1997). We do not detect any significant line emission; our flux estimate for broad-line emission of 1.5 ± 1.0 10 −4 γ/(cm 2-s) is consistent with the spatially-extended flux 1.3 10 −4 γ/(cm 2-s) measured by Bloemen et al. (1997).

Limits on Nuclear Gamma-Ray Emission from Orion
The discovery of -ray line emission in the 3 { 7 MeV range from the Orion complex was recently reported (Bloemen et al. 1994). The observed Compton Telescope (COMPTEL) spectrum suggested that the emission results from the de-excitation of excited states of C and O. We report on a search for these lines using the Oriented Scintillation Spectrometer Experiment (OSSE) on the Compton Gamma Ray Obse...
متن کاملThe L1617 and L1622 Cometary Clouds in Orion
The molecular cloud complex encompassing the cometary clouds L1617 and L1622 is located just outside of Barnard’s Loop in Orion. It lies to the northeast of the Orion Nebula Cluster at a projected distance of 60 pc. The two clouds have radial velocities that differ by about 10 km/s, suggesting that they are not physically associated. Both clouds show evidence for recent, limited low-mass star f...
متن کاملMillion-degree plasma pervading the extended Orion Nebula.
Most stars form as members of large associations within dense, very cold (10 to 100 kelvin) molecular clouds. The nearby giant molecular cloud in Orion hosts several thousand stars of ages less than a few million years, many of which are located in or around the famous Orion Nebula, a prominent gas structure illuminated and ionized by a small group of massive stars (the Trapezium). We present x...
متن کاملThe California Molecular Cloud
We present an analysis of wide-field infrared extinction maps of a region in Perseus just north of the Taurus-Auriga dark cloud complex. From this analysis we have identified a massive, nearby, but previously unrecognized, giant molecular cloud (GMC). Both a uniform foreground star density and measurements of the cloud’s velocity field from CO observations indicate that this cloud is likely a c...

The “ ∫ -shaped filament” of the Orion A giant molecular cloud was mapped in N2H + J = 1→0, and its northern end, the OMC-2/3 region was observed also in HC3N J = 5→4 and CCS JN = 43 → 32 and 76 → 65. The results are compared with maps of other molecular lines and the dust continuum emission. The N2H + distribution is similar to the dust continuum distribution, except for the central part of th...
