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…
Collisional excitation and non-LTE modelling of interstellar chiral propylene oxide
K. Dzenis, A. Faure, B. A. McGuire +7
The first set of theoretical cross sections for propylene oxide (CH3CHCH2O) colliding with cold He atoms has been obtained at the full quantum level using a high-accuracy potential…
Rotational excitation of HO cations by para-H: improved collisional data at low temperatures
S. Demes, François Lique, Alexandre Faure +3
The hydronium cation plays a crucial role in interstellar oxygen and water chemistry. While its spectroscopy was extensively investigated earlier, the collisional excitation of H$_…
Efficient methanol production on the dark side of a prestellar core
Jorma Harju, Jaime E. Pineda, Anton I. Vasyunin +23
We present ALMA maps of the starless molecular cloud core Ophiuchus/H-MM1 in the lines of deuterated ammonia (ortho-NH2D), methanol (CH3OH), and sulphur monoxide (SO). The dense co…
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…
Collisional excitation of NH3 by atomic and molecular hydrogen
N. Bouhafs, C. Rist, F. Daniel +4
We report extensive theoretical calculations on the rotation-inversion excitation of interstellar ammonia (NH3) due to collisions with atomic and molecular hydrogen (both para- and…
Deuteration of ammonia in the starless core Ophiuchus/H-MM1
Jorma Harju, Fabien Daniel, Olli Sipilä +13
Ammonia and its deuterated isotopologues probe physical conditions in dense molecular cloud cores. With the aim of testing the current understanding of the spin-state chemistry of…
Collisional excitation of doubly and triply deuterated ammonia NDH and ND by H
F. Daniel, C. Rist, A. Faure +6
The availability of collisional rate coefficients is a prerequisite for an accurate interpretation of astrophysical observations, since the observed media often harbour densities w…
Interstellar chemistry of nitrogen hydrides in dark clouds
Romane Le Gal, Pierre Hily-Blant, Alexandre Faure +3
The aim of the present work is to perform a comprehensive analysis of the interstellar chemistry of nitrogen, focussing on the gas-phase formation of the smallest polyatomic specie…
