Electron-impact excitation of diatomic hydride cations II: OH and SH
James R Hamilton, Alexandre Faure, Jonathan Tennyson
R-matrix calculations combined with the adiabatic-nuclei-rotation and Coulomb-Born approximations are used to compute electron-impact rotational rate coefficients for two open-shel…
SOFIA/GREAT Discovery of Terahertz Water Masers
David A. Neufeld, Gary J. Melnick, Michael J. Kaufman +6
We report the discovery of water maser emission at frequencies above 1 THz. Using the GREAT instrument on SOFIA, we have detected emission in the 1.296411 THz 8(27)-7(34) transitio…
Hydrogen isotope exchanges between water and methanol in interstellar ices
A. Faure, M. Faure, P. Theulé +2
The deuterium fractionation of gas-phase molecules in hot cores is believed to reflect the composition of interstellar ices. The deuteration of methanol is a major puzzle, however,…
A new nonlocal thermodynamical equilibrium radiative transfer method for cool stars
Julien Lambert, Eric Josselin, Nils Ryde +1
Context: The solution of the nonlocal thermodynamical equilibrium (non-LTE) radiative transfer equation usually relies on stationary iterative methods, which may falsely converge i…
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…
Rotational quenching of H2CO by molecular hydrogen: cross-sections, rates, pressure broadening
Laurent Wiesenfeld, Alexandre Faure
We compute the rotational quenching rates of the first 81 rotational levels of ortho- and para-H2CO in collision with ortho- and para-H2, for a temperature range of 10-300 K. We ma…
