High resolution study of outflows and chemical environment of First Hydrostatic Core candidate Chamaeleon-MMS1
Veronica Allen, Martin A. Cordiner, Gilles Adande +3
The earliest stages of low-mass star-formation are unclear, but it has been proposed that Chamaeleon-MMS1 is a candidate First Hydrostatic Core (FHSC), the transition stage between…
On the accretion process in a high-mass star forming region - A multitransitional THz Herschel-HIFI study of ammonia toward G34.26+0.15
M. Hajigholi, C. M. Persson, E. S. Wirström +8
[Abridged] Our aim is to explore the gas dynamics and the accretion process in the early phase of high-mass star formation. The inward motion of molecular gas in the massive star f…
Cold Water Vapor in the Barnard 5 Molecular Cloud
E. S. Wirström, S. B. Charnley, C. M. Persson +3
After more than 30 years of investigations, the nature of gas-grain interactions at low temperatures remains an unresolved issue in astrochemistry. Water ice is the dominant ice fo…
Isotopic Anomalies in Primitive Solar System Matter: Spin-state Dependent Fractionation of Nitrogen and Deuterium in Interstellar Clouds
E. S. Wirström, S. B. Charnley, M. A. Cordiner +1
Organic material found in meteorites and interplanetary dust particles is enriched in D and 15N. This is consistent with the idea that the functional groups carrying these isotopic…
A spectral line survey of Orion KL in the bands 486-492 and 541-577 GHz with the Odin satellite I. The observational data
A. O. H. Olofsson, C. M. Persson, N. Koning +14
Spectral line surveys are useful since they allow identification of new molecules and new lines in uniformly calibrated data sets. Nonetheless, large portions of the sub-millimetre…
A spectral line survey of Orion KL in the bands 486-492 and 541-577 GHz with the Odin satellite II. Data analysis
C. M. Persson, A. O. H. Olofsson, N. Koning +14
We investigate the physical and chemical conditions in a typical star forming region, including an unbiased search for new molecules in a spectral region previously unobserved. Due…
