The ortho-to-para ratio of water in interstellar clouds
A. Faure, P. Hily-Blant, C. Rist +3
The nuclear-spin chemistry of interstellar water is investigated using the University of Grenoble Alpes Astrochemical Network (UGAN). This network includes reactions involving the…
Depletion and fractionation of nitrogen in collapsing cores
P. Hily-Blant, G. Pineau des Forêts, A. Faure +1
Measurements of the nitrogen isotopic ratio in Solar System comets show a constant value, ~140, which is three times lower than the protosolar ratio, a highly significant differenc…
Modelling the molecular composition and nuclear-spin chemistry of collapsing prestellar sources
P. Hily-Blant, A. Faure, C. Rist +2
We study the gravitational collapse of prestellar sources and the associated evolution of their chemical composition. We use the University of Grenoble Alpes Astrochemical Network…
Challenging shock models with SOFIA OH observations in the high-mass star-forming region Cepheus A
A. Gusdorf, R. Guesten, K. M. Menten +13
OH is a key molecule in H2O chemistry, a valuable tool for probing physical conditions, and an important contributor to the cooling of shock regions. OH participates in the re-dist…
Hyperfine transitions of 13CN from pre-protostellar sources
David Flower, Pierre Hily-Blant
Recent quantum mechanical calculations of rate coefficients for collisional transfer of population between the hyperfine states of 13CN enable their population densities to be dete…
Shocks in dense clouds. IV. Effects of grain-grain processing on molecular line emission
S. Anderl, V. Guillet, G. Pineau des Forêts +1
Grain-grain processing has been shown to be an indispensable ingredient of shock modelling in high density environments. For densities higher than \sim10^5 cm-3, shattering becomes…
