Molecular oxygen in the rho Ophiuchi cloud
B. Larsson, R. Liseau, L. Pagani +56
Molecular oxygen, O2 has been expected historically to be an abundant component of the chemical species in molecular clouds and, as such, an important coolant of the dense interste…
Detection of H2D+ in a massive prestellar core in Orion B
J. Harju, L. K. Haikala, K. Lehtinen +6
Aims. The purpose of this study is to examine the prediction that the deuterated H3+ ion, H2D+, can be found exclusively in the coldest regions of molecular cloud cores. This is al…
Probable detection of H2D+ in the starless core Barnard 68
M. R. Hogerheijde, P. Caselli, M. Emprechtinger +8
The presence of H2D+ in dense cloud cores underlies ion-molecule reactions that strongly enhance the deuterium fractionation of many molecular species. We determine the H2D+ abunda…
Warm Molecular Gas in the Outflow and Envelope of IRAS 12496-7650 (DK Cha)
T. A. van Kempen, M. R. Hogerheijde, E. F. van Dishoeck +3
Aims:To obtain insight into the physical structure of the warm gas in the inner envelope of protostars and the interaction with the outflow. Methods: Sub-millimeter observations of…
Submillimeter spectroscopy of southern hot cores: NGC6334(I) and G327.3-0.6
P. Schilke, C. Comito, S. Thorwirth +5
High-mass star-forming regions are known to have a rich molecular spectrum from many species. Some of the very highly excited lines are emitted from very hot and dense gas close to…
The evolutionary state of the southern dense core Cha-MMS1
A. Belloche, B. Parise, F. F. S. van der Tak +4
Aims: Our goal is to set constraints on the evolutionary state of the dense core Cha-MMS1 in the Chamaeleon I molecular cloud. Methods: We analyze molecular line observations carri…
