SiO line emission from C-type shock waves : interstellar jets and outflows
A. Gusdorf, S. Cabrit, D. R. Flower +1
We study the production of SiO in the gas phase of molecular outflows, through the sputtering of Si--bearing material in refractory grain cores, which are taken to be olivine; we c…
CN in prestellar cores
Pierre Hily-Blant, Malcolm Walmsley, G. Pineau Des Forêts +1
Determining the structure of and the velocity field in prestellar cores is essential to understanding protostellar evolution.} {We have observed the dense prestellar cores L 1544 a…
Molecular line emission in HH54: a coherent view from near to far infrared
T. Giannini, C. McCoey, B. Nisini +4
Aims. We present a detailed study of the infrared line emission (1-200 micron) in the Herbig-Haro object HH54. Our database comprises: high- (R~9000) and low- (R~600) resolution sp…
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…
A quantum-mechanical study of rotational transitions in H2 induced by H
S A Wrathmall, D R Flower
Cross sections have been computed for rotational transitions of H2, induced by collisions with H atoms, using a recent H - H2 potential calculated by Mielke et al. [1]. These resul…
On the excitation of the infrared knots in the HH99 outflow
C. McCoey, T. Giannini, D. R. Flower +1
We present near infrared (IR) spectra (0.98--2.5 mu m) from the group of Herbig-Haro (HH) objects comprising HH99: a series of knots forming a bow, HH99B, and a separate knot, HH99…
