Sulphur chemistry in the envelopes of massive young stars
F. F. S. van der Tak, A. M. S. Boonman, R. Braakman +1
The sulphur chemistry in nine regions in the earliest stages of high-mass star formation is studied through single-dish submillimeter spectroscopy. The line profiles indicate that…
Sulphur chemistry in the envelopes of massive young stars
F. F. S. van der Tak, A. M. S. Boonman, R. Braakman +1
We present submillimeter observations of SO, SO2, H2S, H2CS, OCS, NS and HCS+ toward nine massive young stars. The outflow contributes ~50% to the SO and SO2 emission in 15-20'' be…
Chemistry as a probe of the structures and evolution of massive star forming regions
S. D. Doty, E. F. van Dishoeck, F. F. S. van der Tak +1
We present detailed thermal and gas-phase chemical models for the envelope of the massive star-forming region AFGL 2591. Time- and space-dependent chemistry are used to study the p…
Gas-phase H2O and CO2 toward massive protostars
A. M. S. Boonman, E. F. van Dishoeck, F. Lahuis +2
We present a study of gas-phase H2O and CO2 toward a sample of 14 massive protostars with the Short Wavelength Spectrometer (SWS) on board the Infrared Space Observatory (ISO). Mod…
Highly abundant HCN in the inner hot envelope of GL 2591: probing the birth of a hot core?
A. M. S. Boonman, R. Stark, F. F. S. van der Tak +5
We present observations of the v2=0 and vibrationally excited v2=1 J=9-8 rotational lines of HCN at 797 GHz toward the deeply embedded massive young stellar object GL 2591, which p…
Infrared Observations of Hot Gas and Cold Ice toward the Low Mass Protostar Elias 29
A. C. A. Boogert, A. G. G. M. Tielens, C. Ceccarelli +5
We have obtained the full 1-200 um spectrum of the low luminosity (36 Lsun) Class I protostar Elias 29 in the Rho Ophiuchi molecular cloud. It provides a unique opportunity to stud…
