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…
