Modeling of diffuse molecular gas applied to HD 102065 observations
Cyrine Nehme, Jacques Le Bourlot, Francois Boulanger +2
Aims. We model a diffuse molecular cloud present along the line of sight to the star HD 102065. We compare our modeling with observations to test our understanding of physical cond…
The depletion of NO in pre-protostellar cores
Meltem Akyilmaz, David Flower, Pierre Hily-Blant +2
Understanding the depletion of heavy elements is a fundamental step towards determining the structure of pre-protostellar cores just prior to collapse. We study the dependence of t…
The abundances of nitrogen-containing molecules during pre-protostellar collapse
D. R. Flower, G. Pineau des Forets, C. M. Walmsley
We have studied the chemistry of nitrogen--bearing species during the initial stages of protostellar collapse, with a view to explaining the observed longevity of N2H+ and NH3 and…
The importance of the ortho:para H2 ratio for the deuteration of molecules during pre-protostellar collapse
D. R. Flower, G. Pineau des Forets, C. M. Walmsley
We have studied the evolution of molecular gas during the early stages of protostellar collapse. In addition to allowing for the freeze out of `heavy' species on to grains, we have…
Complete Depletion in prestellar cores
C. M. Walmsley, D. R. Flower, G. Pineau des Forets
We have carried out calculations of ionization equilibrium and deuterium fractionation for conditions appropriate to a completely depleted, low mass pre--protostellar core, where h…
