Far-Infrared detection of methylene
E. T. Polehampton, K. M. Menten, S. Bruenken +2
We present a clear detection of CH2 in absorption towards the molecular cloud complexes Sagittarius B2 and W49 N using the ISO Long Wavelength Spectrometer. These observations repr…
Detection of HCN Direct l-Type Transitions Probing Hot Molecular Gas in the Proto-Planetary Nebula CRL 618
S. Thorwirth, F. Wyrowski, P. Schilke +4
We report the detection of direct l-type transitions towards the proto-planetary nebula CRL 618 during a study of vibrationally excited carbon chains. The J=8,10,11,12,13,14 DJ=0 t…
Physical conditions in the Protoplanetary Nebula CRL 618 derived from observations of vibrationally excited HCCCN
F. Wyrowski, P. Schilke, S. Thorwirth +2
We used the Effelsberg 100m and IRAM 30m telescopes to observe vibrationally excited cyanoacetylene (HCCCN) in several rotational transitions toward the proto-planetary nebula CRL6…
Water Abundance in Molecular Cloud Cores
R. L. Snell, J. E. Howe, M. L. N. Ashby +17
We present Submillimeter Wave Astronomy Satellite (SWAS) observations of the 1_{10}-1_{01} transition of ortho-water at 557 GHz toward 12 molecular cloud cores. The water emission…
Submillimeter Wave Astronomy Satellite Observations of Extended Water Emission in Orion
R. L. Snell, J. E. Howe, M. L. N. Ashby +17
We have used the Submillimeter Wave Astronomy Satellite to map the ground-state 1_{10}-1_{01} transition of ortho-water at 557 GHz in the Orion molecular cloud. Water emission was…
